OPA Gatekeeper pod running out of memory and restarting

With the default limits on OPA Gatekeeper, it is running out of memory due to the large number of constraints and pods it is scanning. This puts it in a restart loop which holds up reconciliation of other packages in Big Bang.

We need to read up on https://github.com/open-policy-agent/gatekeeper/issues/1279 and explore increasing the default memory as well as setting a chunk size.

This must be tested with all packages enabled to insure maximum stress on OPA Gatekeeper.
