This refactors our `ValuesSourceReaderOperator` so it can split pages
when it reads large values. It does not *actually* split the pages as
that's a bit tricky. But it sets the stage for the next PR that will
do so.
* Move `ValuesSourceReaderOperator` to it's own package
* Move many inner classes into their own top level classes
* Extend from `AbstractPageMappingToIteratorOperator` instead of
`AbstractPageMappingToOperator`
* This allows returning more than one `Page` per input `Page`
* In this PR we still always return one `Page` per input `Page`
* Make new `ReleasableIterator` subclasses to satisfy
`AbstractPageMappingToIteratorOperator`
* Change `status` of loading fields from `pages_processed` to
`pages_received` and `pages_emitted`
* Fix a bug in `AbstractPageMappingToOperator` which can leak circuit
breaker allocation if we fail to during `receive`. This isn't possible
in the existing implementations but is possible
in `ValuesSourceReaderOperator`.
* Add a test with large text fields. Right now it still comes back in
one page because we don't cut the pages.
