Subject: Add independent registry auth support

Added the ability to support authentication for independent / 3rd party
registries. This commit will allow users to provide a `oreg_auth_user` and
`oreg_auth_password` to dynmically generate a docker config.json file.

The docker config.json file can be used by openshift to authenticate to
independent / 3rd party registries. `oreg_host` must supply endpoint connection
info in the form of 'hostname.com:port', with (optional) port 443 default.

To update the config.json on a later run, the user can specify
`oreg_auth_credentials_replace=False` to update the credentials.

These settings must be used in tandem with `oreg_url`

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1316341
