spoc merge: add --check

[mhils]

What type of PR is this?

/kind feature

What this PR does / why we need it:

This PR adds a --check flag to spoc merge. This can be used to ensure that (automatically generated) profiles are subsets of a (hand-authored) profile in CI. This is better than manually calling diff as we ignore non-essential syntax such as comments.

Which issue(s) this PR fixes:

None

Does this PR have test?

Not yet.

Special notes for your reviewer:

Does this PR introduce a user-facing change?

`spoc merge` now has a `--check` flag to ensure that a profile is a superset of other profiles.

Hi @mhils. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.
