* client: improve group service stanza interpolation and check_restart support

Interpolation can now be done on group service stanzas. Note that some task runtime specific information
that was previously available when the service was registered poststart of a task is no longer available.

The check_restart stanza for checks defined on group services will now properly restart the allocation upon
check failures if configured.

Michael Schurter 8634533e82 client: expose group network ports in env vars 
Fixes #6375

Intentionally omitted IPs prior to 0.10.0 release to minimize changes
and risk.

Mahmood Ali 7a32d3f3aa client: handle 0.8 server network resources 
Fixes https://github.com/hashicorp/nomad/issues/5587

When a nomad 0.9 client is handling an alloc generated by a nomad 0.8
server, we should check the alloc.TaskResources for networking details
rather than task.Resources.

We check alloc.TaskResources for networking for other tasks in the task
group [1], so it's a bit odd that we used the task.Resources struct
here.  TaskRunner also uses `alloc.TaskResources`[2].

The task.Resources struct in 0.8 was sparsly populated, resulting to
storing of 0 in port mapping env vars:

```
vagrant@nomad-server-01:~$ nomad version

        "MBits": 10,
        "ReservedPorts": null
      }
    ]
  }
}
```

Also, updated the test values to mimic how Nomad 0.8 structs are
represented, and made its result match the non compact values in
`TestEnvironment_AsList`.
