----------------------------------------

Provided a check to validate the partition exist or not if it exists remaining execution it will skip and execution will complete.

> INSERT OVERWRITE TABLE X PARTITION (a=b, c=d) IF NOT EXISTS ...
> The partition should be created and written if and only if it's not there already.
> The support can be added for dynamic partitions in the future, but this jira is for adding this support for static partitions.
