There was no maximum limit set for the number of maximum histograms
bucket, which can lead to a crash in case of higher value.
PG-382: Adjust the maximum value for histogram buckets.
Fix the regression issue related to GUC and set the maximum
buckets value correctly.
PG-382: Adjust the maximum value for histogram buckets.

This commit brings following changes to this branch:
1) Port changes/additions TAP testing from main branch to this branch, under PG-292.
2) Changes to test cases due to GUCs change, under PG-331.
3) Call counts verfications, under PG-338.
4) Changes to github workflows to accomodate automation for TAP testing, under PG-343.
Changed the default value of pgsm_bucket_time from 300 to 60. Now neither PMM users will need to adjust the default value, nor
restart of PG server will be required for this purpose.
