Using self-signed certs with MinIO blobstore

[a2geek]

This is likely mostly some documentation note for other users/tinkerers. If you are using self-signed certificates (like using the minio-genesis-kit), there are a couple of different patches that need to be added.

For the environment configuration, Fog does have the capability to ignore the self-signed certificate:

bosh-variables:
  fog_connection:
    connection_options:
      ssl_verify_peer: false

But, in addition, the rep needs to also be told to allow the self-signed certificate (yaml-patch syntax):

---
- type: replace
  path: /instance_groups/name=diego-cell/jobs/name=rep/properties/diego/ssl?/skip_cert_verify
  value: true

This wasn't obvious and hopefully saves somebody else spending time tracking those details down.
