This is an automated cherry-pick of #48870

What problem does this PR solve?

Issue Number: close #48869

Problem Summary:

What changed and how does it work?

Prior to this commit, each auto id allocator has it's own autoid client (a grpc connection inside), so if we have 60K tables there would be 60K tcp connections ...

After the fix, the autoid client is moved to domain so there should be only one autoid client instance. All the autoid allocator share this instance now.

Check List

Tests

  • Unit test
  • Integration test
  • Manual test (add detailed scripts or steps below)

See the reproduce steps in the issue.
The test check tcp connection counts, it's harder to do that in unit test

  • No need to test
    • I checked and no code files have been changed.

Side effects

  • Performance regression: Consumes more CPU
  • Performance regression: Consumes more Memory
  • Breaking backward compatibility

Documentation

  • Affects user behaviors
  • Contains syntax changes
  • Contains variable changes
  • Contains experimental features
  • Changes MySQL compatibility
