[TRAFODION-2457] Re-enable compGeneral/TEST042 and try to stabilize
Implemented suggestions made by Suresh and Selva. Suresh found out
that the test gives different results when authorization is
initialized, and that caused problems because it is usually
initialized on developer workstations but not on Jenkins.
Suresh and Selva suggested to suppress the key length, since that can
vary with different CQD settings like SCHEMA.
Added the queries to the log and expected files to see whether that
will make failure diagnosis easier. The queries get filtered out, so
should not cause test failures.

> Project: Apache Trafodion
> Issue Type: Bug
> Reporter: Anoop Sharma
> Assignee: Hans Zeller
>
> compGeneral/TEST042 runs tests for query caching feature and
> validates it by looking at the number of cache hits and other parameters.
> These values change based on where this test is being run,
> what the environment is and other changes.
> It fails off and on and folks have been updating expected files
> or known diff files to handle it.
> Because of the non-deterministic behavior, the test as it is currently
> written is unreliable and developers/jenkins failures are ignored.
> The test suite need to be modified and written so it doesn't make
> the cache hit/miss values as part of expected output. Or some other
> way to tolerate a range or the difference in output.
> For this checkin, this test has been disabled. A proper way to write
> this test will be discussed and once that is done, it will be reenabled.
