Service Manifest Templating

[nyodas]

ggn should be able to template it's own manifest.

We would have to read the attributes from the command line and the attributes folder.
If the attributes are provided on the command line could be stored in etcd to be able to resolve template for the people that do not have the proper configuration.

• Deploy the service front with a particular version on the command line.
  • The version is available to be handled for the other user of the cluster.
