Parser support for adding/removing partition

[okhowang]

partition syntax has been supported in dolthub/go-mysql-server#2472.
but adding/removing partition remain error in parser.

alter table a partition by hash ( id );
alter table a remove partitioning ;

Hi @okhowang, thanks for taking the time to report this. Adding parser support for this syntax in our fork of vitess should be pretty straightforward. We're all focused on other tasks currently, but we'll see if we can knock this one out quickly as we get some open time. If anyone is looking to make a contribution, this is a pretty good one to start with, and we're happy to provide pointers.

@jycor would this one take long to knock out?

Hey @okhowang, the fix for this has been merged to dolt main. We'll have a release out with the fix later this week.
