* Address OCSP client caching issue
- The OCSP cache built into the client that is used by cert-auth
would cache the responses but when pulling out a cached value the
response wasn't validating properly and was then thrown away.
- The issue was around a confusion of the client's internal status
vs the Go SDK OCSP status integer values.
- Add a test that validates the cache is now used
* Add cl
* Fix PKI test failing now due to the OCSP cache working
- Remove the previous lookup before revocation as now the OCSP
cache works so we don't see the new revocation as we are actually
leveraging the cache
