revert default compression engine

[rvrangel]

Signed-off-by: Renan Rangel rrangel@slack-corp.com

Description

As part of #10558, it seems we have changed the default compression engine from pargzip to pgzip. We can see here that this was the compressor used before. Currently we are defaulting to pgzip and that is not intended as it was moved from pgzip => pargzip in #7037

This will make sure the default engine is pargzip again, as there is a considerable difference on resource usage when using the other engine.

LGTM. You will need to change the expected output for flags_test

You need to fix the test case failures

Run endtoend tests on Cluster (21)
isn't reporting any status .. not sure why .. it has backup/restore tests ... I think we should run them before sign-off..

Looks like there might have been a problem with GH Actions.
@rvrangel the only way to kick it is to make an empty commit and push again.
