Autodetect certificate secret type

[ramondeklein]

It may be required to set the secret type, when using externalCertSecret, externalCaCertSecret or clientCertSecret to make sure the operator mounts the certificate correctly. The type can also be auto-detected by inspecting the secret. This would make configuration easier and less error-prone.

The downside is that secrets need to be fetched, but a secret informer could be used to reduce the additional load of fetching certificates. I think it's worth the trade-off.
