jira TRAFODION-2234 turn aligned format on, phase 1

This is phase 1 of aligned format change.

Dev regressions now run with aligned format tables.

To test both hbase and aligned format, some tests have explicit

specification to create hbase format tables.

Tests that test for features that are currently only available

with hbase format (like pushdown sel expr) create hbase format tables.

Many expected files have been updated to reflect aligned format,

mostly in showddl and explain output.

[TRAFODION-1823] ESP idle timeout does not kick in, leading to too many ESPs on the system

Close message from the master was not sent to ESP by the platform

agnostic messaging layer in Trafodion. Fixed this bug and then ESP idle time

works as expected.

ESP_IDLE_TIMEOUT can now be given as a CQD. Internally, it would be

changed to SET SESSION DEFAULT and used by the IPC layer of Trafodion.

ESP_IDLE_TIMEOUT is set to 30 minutes by default in the CQD too.

Added test in core/TESTRTS to test ESP_IDLE_TIMEOUT

[TRAFODION-1771] Enabled TESTRTS again TESTRTS was failing at times with error 8926. This is due to absence of ROOT_OPER_STATS in statistics area, but the stats descriptor was incorrectly indicating that there is a ROOT_OPER_STATS.

In future, I will get rid of setting the accumulated statistics as part of

cleanup effort of the statistics collection.
