[Schema modification] Change schema modification process to be processed by worker

Description

The provisions tasks are being impacted by the schema modification queue. We should move it to a different worker. However, when we tried in https://totvslabs.atlassian.net/jira/software/c/projects/CAPL/boards/18?modal=detail&selectedIssue=CAPL-3846, the worker could not handle the schema modification process and kept dying and restarting.

The worker was dying because of this query:

Now that the query’s issue is solved we must move the schema modification process to worker again, and since it processes other tasks we must increase its memory to 2Gi.
