zun: add hostname, hints and security_groups

Add three properties to the container resource: hostname,
hints and security_groups. The 'hostname' is the hostname of
the container. The 'hints' is a set of key-value pair passed
to the scheduler. The 'security_groups' is a list of neutron
security groups.
