ridwanmsharif sql, settings: add a version for CascadingZoneConfigs

This is meant for the 2.1-1 version. It updates the version file
and some tests that rely on it. When the cluster version is higher,
then and only then will the cascading zone configs take hold.
Also changes output of the `SHOW ZONE CONFIGURATIONS` command
to only show explicitly set fields.

Release note (sql change): Changes the result for `show all zone
configurations` and `show zone configuration for ...`. Also
changes how zone configuration changes behave.
