Run make generate, make generate-limits, and remove soak tests

[jdn5126]

What type of PR is this?
cleanup

Which issue does this PR fix?:

N/A

What does this PR do / Why do we need it?:
This PR does the following:

1. Runs make generate to update generated files.
2. Runs make generate-limits to update instance limits.
3. Removes the soak integration test suite, as the checkpoint migration has been completed and this suite is no longer relevant.

One thing to call out is how significant the changes in rpc/rpc.pb.go are. These come from running: protoc --go_out=plugins=grpc,paths=source_relative:. rpc.proto with protoc version libprotoc 3.15.8. From review, these changes look correct and safe to me.

Testing done on this change:
All unit tests and integration tests pass.

Will this PR introduce any new dependencies?:
No

Will this break upgrades or downgrades? Has updating a running cluster been tested?:
No, Yes

Does this change require updates to the CNI daemonset config files to work?:
No

Does this PR introduce any user-facing change?:
Yes

Updates instance limits and generated RPC code

Agree.

For auto-generated code, relying on Integration tests are the best.
