Passing custom certificates for master public url

[ioggstream]

I wish

to pass custom certificates for master public url (actually the lb hostname).

I thought

1. to pass them like ca_certificate.yaml so that cloud-init can create them in a static position
2. if the params are set, OSv3.yml looks for them in that position

ideas?

Other thoughts? I thought to use some other service to (Eg. switft ) to avoid continuously passing keys around.

As I'm going to implement this soon, so I hope to get some feedback helping the eventual merge of the patch ;)
