Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:
- [ ] Make sure to open an issue as a [bug/issue](https://togithub.com/googleapis/java-spanner/issues/new/choose) before writing your code!  That way we can discuss the change, evaluate designs, and agree on the general idea
- [ ] Ensure the tests and linter pass
- [ ] Code coverage does not decrease (if any source code was changed)
- [ ] Appropriate docs were updated (if necessary)

Fixes #<issue_number_goes_here> ☕️

If you write sample code, please follow the [samples format](

* feat: Add Metrics host for built in metrics (#3519)

This PR allows users to set the custom monitoring host for built in metrics.

* feat: introduce java.time variables and methods (#3495)

This PR introduces `java.time` alternatives to existing `org.threeten.bp.*` methods, as well as switching internal variables (if any) to `java.time`

The main constraint is to keep the changes backwards compatible, so for each existing threeten method "`method1(org.threeten.bp.Duration)`" we will add an alternative with a _Duration_ (or _Timestamp_ when applicable) suffix: "`method1Duration(java.time.Duration)`".

For most cases, the implementation will be held in the `java.time` method and the old threeten method will just delegate the call to it. However, for the case of abstract classes, the implementation will be kept in the threeten method to avoid breaking changes (i.e. users that already overloaded the method in their user code).

* test: enable more tests on the Emulator (#3535)

Multiple tests were skipped on the Emulator, because the features that
are covered by these tests were originally not supported on the
Emulator. These features are now available on the Emulator, and the
tests can be enabled.

* ci(spanner): Fix nightly job issues (#3522)

* ci(spanner): Fix nightly job permission issue

* update scope for surefire-junit4

* chore: add internal option for statement executor type (#3534)

The Connection API by default uses either a platform thread or a virtual thread
for each connection to execute and control the statements of that connection. This
is used to enable asynchronous execution of statements and allows a statement to
be cancelled by just interrupting this thread. Both these use cases are however
not (or only very rarely) used by the most common users of the Connection API;
the JDBC driver and PGAdapter. PGAdapter uses the PostgreSQL wire-protocol, which
by design is synchronous, and JDBC is also a synchronous API. The latter has a
cancel() method that currently requires this threading model, but this can be
modified in the JDBC driver.

Using a direct executor instead of a single-threaded executor per connection can
save one thread per connection.

The option is intentionally made package-private, so the above-mentioned
frameworks can set it by default without it becoming part of the public API.

* feat: support 'set local' for retry_aborts_internally (#3532)

Adds support for `set local retry_aborts_internally=true|false` in the
Connection API. This change also adds the parsing infrastructure that is
needed to support `set local` for all connection variables. Support for
this will be added to other connection variables in follow-up pull requests.

* feat: add opt-in for using multiplexed sessions for blind writes (#3540)

* feat(spanner): Releasing Multiplexed session for blind write.

* fix(spanner): Added exception for `setUseMultiplexedSessionBlindWrite` in Clirr check. Removing this is safe as it's not used by customers.

* fix(spanner): Fixed unit test for multiplexed session.

* chore: reset default to platform thread (#3551)

Reset the default to using a platform thread for connections. This was the
default before adding an option for setting the executor type, and the new
default is causing problems with the async Connection API.

* chore: make valid connection properties public (#3546)

Make the list of valid connection properties public, so tools that
depend on the Connection API can use this to for example generate
documentation for valid properties.

Also add valid values to the connection properties that have that
(e.g. enums and booleans).

* chore: make internal auth backend errors retryable

Spanner occasionally returns INTERNAL errors regarding the auth backend server.
These errors should be regarded as retryable.

* fix: retry specific internal errors

Some specific internal errors should be retrid. Instead of adding INTERNAL
as a standard retryable error code, we use an interceptor to catch and
translate those specific errors.

* chore: address review comments

* fix: wait for session pool to initialize

* fix: register errors before creating the client

* chore: disable native metrics when there are no credentials (#3567)

* chore: disable native metrics when there are no credentials

Native metrics were automatically disabled when the emulator is used, but
some clients (e.g. PGAdapter) set up the connection to the emulator manually
instead of setting the environment variable. Also, when using in-mem mock
servers, native metrics should be disabled, as they cannot be exported.

This PR therefore adds an additional check that disables native metrics
when the client uses a NoCredentials instance.

* chore: make method private

There are SPANNER_SYS tables that contain ARRAY<STRUCT> columns. Adding support for this in the CloudClientExecutor so that queries involving these tables do not throw an error.

Aborted transactions should ideally be retried in the same transaction manager instance because the client library will ensure to populate the "Prev txn attempt's txn id" on retry (for mux sessions) which helps preserve the lock order(priority) of the transaction in scenarios of high contention thats causing txn wounding. This is achieved by using `resetForRetry()` that automatically takes care of preserving the lock order.

But if the customer application retries aborted transactions on a new TransactionManager instance with out using the `resetForRetry()`, we lose the lock order of the previous attempt.

To address this scenario of preserving the lockorder across transaction manger instance for a retry of the same transaction
Current proposal as per client lib team recommendation:
1. Overload the [Begin](https://togithub.com/googleapis/java-spanner/blob/9940b66dabe519495a69dcc0020e2587c16f7285/google-cloud-spanner/src/main/java/com/google/cloud/spanner/TransactionManager.java#L62) API in the TransactionManager to accept an AbortedException argument.
2. Client library will populate the aborted transaction's transaction ID in the [AbortedException](https://togithub.com/googleapis/java-spanner/blob/efb168015aee1c4cba16f666b89be19e6f04fdbe/google-cloud-spanner/src/main/java/com/google/cloud/spanner/AbortedException.java#L27) object which is propagated up the customer's application stack.
3. On the customer end, they will just need to pass in this AbortedException object to the "Begin" API when they retry the transaction on the new transaction manager instance.

Note: This will be a no-op for regular sessions.
