Registry Persistence through Minio

Registry: begin integration with Minio chart

Setup the Registry to work with the Minio chart.

• Add configuration for minio. Need enable, bucket, credentials secret
• Add credentials means adding an initContainer to plug thos credentials in
• Modify the mounts to use projected, and initContainer pattern
  • Small cleanup of the certificates mounting logic to get static names.
• Add logic, so that if no storage and minio.enabled: false, use filesystem driver with /tmp/registry to ensure permissions function (securityContext)

This is the first stages.

Depends #184 (closed) !113 (merged)

• Minio needs exposed through the Ingress
  • Security on the buckets needs to be confirmed, as we're exposing the whole shebang.
  • We'll need/want to investigate exposing the UI
• We'll need to incorporate globals for Minio, to get the hosts/acme/ingress

Closes #113 (closed)
