[TRAFODION-3280] Reduce path length in Trafodion for improved performance and
scalability
URL: https://github.com/apache/trafodion/pull/1820
This PR fixes the following issues to improve performance.
1. When the session is dropped for the default context, we were
unnecessarily dropping HBase connections.
2. There were 2 HBase connections per mxosrvr - one for the default context
and another for repository context. Now it has been changed to one HBase
connection per process.
3. cli_globals::currContext() is now optimized for default context.
4. Changes to ensure that logging related objects are created and the
corresponding functions are called only when the logging Level is set higher
than the recording level,

> To improve OLTP kind of queries, a sample application was profiled to
> determine the unnecessary dominant functions in Trafodion. It is found that
> # JULIANTIMESTAMP was abnormally taking longer path length.
> # Unnecessary memset after malloc because new and delete operators were
