feat(restic): support for using an existing pvc as a repository

[onedr0p]

Describe what this PR does

Support for using an existing pvc as a restic repository, opens up the ability to use NFS backed volumes (and others) to store the backup repository on instead of only using s3

Is there anything that requires special attention?

Hi @onedr0p. Thanks for your PR.

I'm waiting for a backube member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

@JohnStrunk is this what you had in mind from our discussion from awhile ago in #321?

[JohnStrunk]

We haven't forgotten about this one... Things have been busy. We'll take a look when we get a chance.

No worries, I am actually using a kyverno policy to mutate the job to add this support in the meantime.
