Remove the isXdsSniEnabled environment variable guard and the legacy logic that falls back to the channel authority for SNI. This aligns the implementation with gRFC A101, ensuring no SNI is sent if it is not explicitly determined by xDS configurations. Update the test suite by removing the isXdsSniEnabled flag and deleting test case that specifically verified behavior when the flag was set to false. Additionally, add a new test case to verify that SNI is omitted when none of the A101 conditions are met, ensuring the SNI field is not sent in the TLS handshake. Ref grpc#11784

Description
Remove the
isXdsSniEnabledenvironment variable guard and the legacy logic that falls back to the channel authority for SNI. This aligns the implementation with gRFC A101, ensuring no SNI is sent if it is not explicitly determined by xDS configurations.Changes
Update the test suite by removing the
isXdsSniEnabledflag and deleting test case that specifically verified behavior when the flag was set to false. Additionally, add a new test case to verify that SNI is omitted when none of the A101 conditions are met, ensuring the SNI field is not sent in the TLS handshake.Note for Reviewers
Some test files show large diffs because of re-indentation after removing
try-finallyblocks (since theisXdsSniEnabledflag is no longer needed). I recommend reviewing these files with the 'Hide whitespace changes' option enabled.Ref #11784
