Test Improvements

Changes
-------
* Moved tracing/metrics query index mgmt tests to use the default test bucket
* Moved views tests to use a new bucket to avoid potentially picking up
  documents from other tests
* Added retries to bad CAS transactions tests
* Increased timeouts in certain test scenarios
* Added retries for metrics datastructure tests
