Impelement secrets detection for Az modules

[vidai-msft]

This pull request introduces changes primarily focused on adding a new feature for detecting and warning about potential secrets in the output of Azure PowerShell commands. The changes span across multiple files, with the addition of a new Sanitizer class and modifications to existing classes to incorporate the use of this new class.

Here are the most important changes:

New feature for secrets detection:

• src/Authentication.Abstractions/Models/ConfigKeysForCommon.cs: Added a new constant ShowSecretsWarning to the ConfigKeysForCommon class. This constant will be used to control whether the new secrets detection feature is enabled. It is disabled by default for now.

• src/Common/AzurePSCmdlet.cs: Added a new Sanitizer object and methods for detecting secrets in the output of Azure PowerShell commands. The Sanitizer object is used in the WriteObject methods to sanitize the output before it's written to the pipeline. If any secrets are detected, a warning message is written to the console in the WriteShowSecretsWarningMessage method.

• src/Common/MetricHelper.cs: Modified the PopulatePropertiesFromQos method and the AzurePSQoSEvent class to include information about detected secrets in the telemetry data.

• src/Common/Properties/Resources.Designer.cs and src/Common/Properties/Resources.resx: Added a new localized string ShowSecretsWarningMessage for the warning message displayed when secrets are detected in the output.

• src/Common/Sanitizer/AzurePSSanitizer.cs, src/Common/Sanitizer/DefaultProviderResolver.cs, src/Common/Sanitizer/DefaultSanitizerSettings.cs: Added new classes for the Sanitizer object used for detecting secrets in the output. The AzurePSSanitizer class contains the main logic for sanitizing objects and detecting secrets. The DefaultProviderResolver and DefaultSanitizerSettings classes provide additional support for the sanitization process.

• The main logic to detect secrets in the output object is to traverse each property of this object with pre-defined types, which are SanitizerCollectionProvider, SanitizerDictionaryProvider, SanitizerJsonArrayProvider, SanitizerJsonObjectProvider, SanitizerStringProvider. If later on, new types are necessary, new providers as classes will be added and no existing class modification is needed.

1. Overall, we should minimize public types in common repo, because more public stuff means more dependencies, and more dependencies makes it difficult to maintain.
2. Instead of instanciate AzurePSSanitizer for every cmdlet, consider designing it as a singleton component like IConfigManager. This is for performance.

Following changes were made.

1. ISanitizerSettings was renamed to ISanitizerService and the methods were also updated per discussion.
2. Moved DefaultSanitizerService and AzurePSSanitizer from out of common to Az.Accounts.
