Remove eTag from RevisionResource, subject to experiment

In https://gerrit-review.googlesource.com/c/gerrit/+/293978, eTag was
removed from GetRevisionActions, but not RevisionResource. This resulted
in the UI to show stale 'submit' action on the change in the same
submission chain. The UI now uses RevisionResource eTag, that does not include
MergeSuperSet (all related changes).

In this change:
- Return non-cacheable result from GetRevisionActions, so it does not
return RevisionResource eTag.
- Add an experiment flag to remove revision eTag. The computation of eTag
can be expensive, we can run experiments to see if it can be dropped
permanently.
