multi-target: Enable management of multiple target machines

This patch modifies lava-dispatcher to allow it to manage tests
that require synchronized actions across multiple machines.

The main thread launches a child thread for each target and then
waits for child threads to complete.

Each child thread is given a list of actions constructed from the
json job file.

Changes to job file format:
Multi-target jobs should include a "client_groups" attribute
containing one or more named groups of target machines, e.g.:

    "client_groups": [
        {
            "name": "target_group",
            "target_hosts": [
                "host1", "host2"
            ]
        },
        {
            "name": "helper_group",
            "target_hosts": [
                "host3"
            ]
        }
    ]

    "target_hosts" lists may include ip addresses and ip address
ranges ("xxx.xxx.xxx.xxx-yyy.yyy.yyy.yyy").

    Each action in a multi-target job includes a list of target
groups, e.g.:

"target_groups" = ["target_group", "helper_group"]

Synchronization may be written in the action implementations.
If job-script-level synchronization is desired, the provided
sync_to_label action will cause all members of all groups in
its "target_groups" list to wait for all other members to reach
that action before continuing.

Both client- and server-side results for all clients are
collected and submitted by the "submit_results" action.
