Run more of the tests that have been ignored or missed

[Xtansia]

Description

This PR ensures more of the tests that have been ignored or missed are actually run:

• Tests.Reproduce was not running due to a missing dependency on xunit.runner.visualstudio
• There was a reproduce test lost under a Reproduce folder outside the test project
• Integration tests were only being run in the Tests project, not those in Tests.Reproduce
• Fix broken reproduce tests that hadn't been being run
• Run the tests related to "abstractions"
• Remove references to OpenDistro/ODFE as it has been completely archived and the downloads no longer function

@Xtansia do you know why Tests.Reproduce.GitHubIssue4537.CanDeserializeSnapshotShardFailure test failed in the Create Release Candidate workflow?

[Yury-Fridlyand]

There is a flaky test in Reproduce. I rerun the workflow and now it pass.

[Yury-Fridlyand]

Actually, there are more than 100 not executed integration tests and few dozens of deactivated UT and IT.
Just a fact, it is not a proposal to fix them in scope of one PR.

Is this just related to tests with [Skip] attributes, or some larger group?

[Yury-Fridlyand]

Unfortunately, there is larger group.
Tests with [Skip] are deactivated due to some bugs or limitations of specific product version.
