authorize: implement client certificate CRL check (#4439)
Update isValidClientCertificate() to also consult the configured certificate revocation lists. Update existing test cases and add a new unit test to exercise the revocation support. Restore the skipped integration test case. Generate new test certificates and CRLs using a new `go run`-able source file.
