Recreate certificates that are only specified to be used as server certs #2767

Description

Old clusters from before Calico Enterprise v3.13 created certificates
that were only valid as server certs.

In v3.17, we have updated these connections to use mTLS, and so these
certs are also used as client certs.

This PR updates the operator to spot when certificates issued by the
tigera-operator-signer do not have the necessary ExtUsageKeyClientAuth
usage, and regenerates them if so.

For PR author

  • Tests for change.
  • If changing pkg/apis/, run make gen-files
  • If changing versions, run make gen-versions

For PR reviewers

A note for code reviewers - all pull requests must have the following:

  • Milestone set according to targeted release.

    • kind/bug if this is a bugfix.

LGTM, with a few possible nits. (But I am not an operator dev, so I am sure you will want an approval from one of them, and hence have not marked as approved myself.)
