a0bd790005 ColumnStore Cache changes. 
1. Add a new system variable, columnstore_use_cpimport_for_cache_inserts,
  that when set to ON, uses cpimport for the cache flush into ColumnStore.
  This variable is set to OFF by default. By default, we perform batch inserts
  for the cache flush.

  2. Disable DMLProc logging of the SQL statement text for the cache
  flush operation in case of batch inserts. Under certain heavy loads
  involving INSERT statements, this logging becomes a bottleneck for
  the cache flush, causing subsequent inserts into the cache table to hang.

4fc7fa12cd MCOL-129 INSERT/UPDATE strict mode support 
This changes the warning for truncation to the correct MariaDB error
code (1264).

In addition it passes the strict mode up into the DML class to roll back
correctly.

It also sets the abort_on_warning flag for updates as this isn't set on
the rnd_init phase but is needed for strict mode to work.
