This PR adds functionality to the xdsclient transport to send the node proto only on the first request on the stream. If the stream breaks, the node proto will be sent on the first request of subsequent streams as well.

Other changes in this PR (mostly testing related)

  • New tests to verify behavior added in this PR.
  • Move the testResourceWatcher type from authority_test.go into xds/internal/testutils package, and export it.
  • Update authority_test.go to use the new TestResourceWatcher type exported above.
  • Enable the fakeserver.Server to be started with a net.Listener provided by the test.

Fixes #5668.

RELEASE NOTES:

  • xdsclient: send Node proto only on first discovery request on ADS stream
