K8SPS-96 compressed backups improv

[gkech]

CHANGE DESCRIPTION

Problem:

Compression can be configured using the configuration option of mysql defined in CR, as well as arguments. The status of backups that are compressed should consider that possibility and reflect that.

Also changing the default algorithm used for the e2e tests for compression, since we are observing issues related to that: https://perconadev.atlassian.net/browse/PXB-3568

Cause:
Short explanation of the root cause of the issue if applicable.

Solution:
Short explanation of the solution we are providing with this PR.

In general this is okay, but did we consider using something like go-ini to automatically parse such config?

[gkech]

Good point! I'm planning of extracting the logic from cmd/bootstrap/gr/config.go to a shared package, exported, etc and reuse it here. I'm going to open that in a new PR cause the e2e tests are already running and it can be just an improvement.
