This is a backport of #12502

…io#12502)

* Use new healthy shard check in vreplication e2e tests

This is needed because checking that there's a primary tablet for
the shard in vtgate's healtcheck is no longer a reliable indicator
that the shard has a healthy serving primary, because now a
primary needs to initialize its sidecar database and wait for
that to replicate via semi-sync before it becomes serving and can
proceed to perform normal functions. So this delay could cause
test flakiness if you required a healthy shard before continuing
with the test.

* Try to address unit test race flakes around log size

And they most often occurred in the wrangler unit tests, which makes sense
because it creates a log of loggers.

Review Checklist

Hello reviewers! 👋 Please follow this checklist when reviewing this Pull Request.

General

  • Ensure that the Pull Request has a descriptive title.
  • If this is a change that users need to know about, please apply the release notes (needs details) label so that merging is blocked unless the summary release notes document is included.
  • If a test is added or modified, there should be a documentation on top of the test to explain what the expected behavior is what the test does.

If a new flag is being introduced:

  • Is it really necessary to add this flag?
  • Flag names should be clear and intuitive (as far as possible)
  • Help text should be descriptive.
  • Flag names should use dashes (-) as word separators rather than underscores (_).

If a workflow is added or modified:

  • Each item in Jobs should be named in order to mark it as required.
  • If the workflow should be required, the maintainer team should be notified.

Bug fixes

  • There should be at least one unit or end-to-end test.
  • The Pull Request description should include a link to an issue that describes the bug.

Non-trivial changes

  • There should be some code comments as to why things are implemented the way they are.

New/Existing features

  • Should be documented, either by modifying the existing documentation or creating new documentation.
  • New features should have a link to a feature request issue or an RFC that documents the use cases, corner cases and test cases.

Backward compatibility

  • Protobuf changes should be wire-compatible.
  • Changes to _vt tables and RPCs need to be backward compatible.
  • vtctl command output order should be stable and awk-able.
  • RPC changes should be compatible with vitess-operator
  • If a flag is removed, then it should also be removed from VTop, if used there.

LGTM. How about gathering all flakes backport onto a single PR to avoid overloading the CI?
