Exporter isn't compatible with Native TLS Secrets

Attempting to use exporter with a TLS configured cluster fails because the appropriate cert/key/ca's aren't being mounted into the side car and passed along to the exporter application.

The fix for this is straightforward, although there is room for nuance with the Native TLS style of secrets as we may have multiple Root CA's and so questions remain as to how would this should work in conjunction with the exporter.
