What problem does this PR solve?

Issue Number: close #57585

Problem Summary: Some values from the command line are not properly redacted.

  • --full-backup-storage
  • --crypter.key
  • --log.crypter.key
  • --azblob.encryption-key
  • --master-key (the current implementation of this may be too conservative)

Check List

Tests

  • Unit test
  • Integration test
  • Manual test (add detailed scripts or steps below)
  • No need to test
    • I checked and no code files have been changed.

Side effects

  • Contains syntax changes
  • Contains variable changes
  • Contains experimental features
