PG-607: Allow histogram to track queries in sub-ms time brackets (#384) 

* PG-607: Allow histogram to track queries in sub-ms time brackets

Updated the GUC configuration and the relevant histogram functionality
to track queries in lower cardinality than ms. This is done by saving
the GUC values for histogram min and max values in real (double) type.

All test cases except for the 030 tap test are passing. The test case
needs an update.

* Fixing regression issues for v12 and below because of histogram changes.
