Add QueryObfuscator tests/benchmarks, fix for bearer

[smola]

What Does This Do

• Added more tests and JMH benchmarks for QueryObfuscator.
• Fix for redaction of bearer tokens.

Motivation

I saw some potential performance optimizations for the default QueryObfuscator regular expression (not included in this PR), so I added these tests and benchmark to try them.

While testing this, I noticed that Bearer token forms were not fully redacted, fixed this case.

Additional Notes

I'll try to follow up with the optimized regular expression.
