[bug] After the problem that is v0.40.0-beta.0 and etcd quota, recovering from it is currently troublesome

[samip5]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

After running v0.40.0-beta.0 before seeing that it had an etcd related bug, the updates version without the bug cannot be started due to Error: failed to run Omni: failed to create concurrency session: etcdserver: mvcc: database space exceeded

Expected Behavior

I expected there to be a way to customize QuotaBackendBytes for etcd, but there appears to not be.

Steps To Reproduce

1. Run v0.40.0-beta.0 for a while
2. Update to v0.40.0
3. See it fail to start

What browsers are you seeing the problem on?

No response

Anything else?

There is no disk pressure on the system, so that error doesn't make any sense.
