Multiple: Check optimizer_control before updating optimizer
JIRA: MADLIB-1109
This is applicable only for the Greenplum and HAWQ platforms:
We disable/enable ORCA using the 'optimizer' GUC in some functions for
performance reasons. GPDB/HAWQ has another GUC 'optimizer_control' which
allows the user to disable updates to the 'optimizer' GUC. Updating
'optimizer' when 'optimizer_control = off' leads to an ugly error.
This commit adds a check for the value of 'optimizer_control' and
updates 'optimizer' only if 'optimizer_control = on'.
