legacy ssl configuration is missing

[Márton Kiss]

When the ssl_ca, ssl_cert, ssl_key config options defined, the endpoints are not using TLS at all:

  masakari:
    options:
      ssl_ca: *ssl_ca
      ssl_cert: *ssl_cert
      ssl_key: *ssl_key
  ...

Endpoint list:

$ openstack endpoint list -c "Service Name" -c "URL" -f value | grep "masakari"
masakari http://masakari-internal.mydomain.com:15868/v1/%(tenant_id)s
masakari http://masakari.mydomain.com:15868/v1/%(tenant_id)s
masakari http://masakari-internal.mydomain.com:15868/v1/%(tenant_id)s

This bug should be similar to placement charm's when, where this fix was the solution:
