Driver plakar

[cvaroqui]

Work in progress status.

resource status is still to do for example.

Example resource config in a test/svc/plakar:

[sync#0]
type = plakar
#schedule = @1m
store_config = key store from ./sec/{name}
passphrase = key passphrase from ./sec/{name}
policy_config = key policy from ./sec/{name}

With datastore referenced keys like:

root@dev4n1:~/dev/om3# om test/sec/plakar key decode --name store
plakar.test.svc.cluster1:
  location: /root/plakar/backup

root@dev4n1:~/dev/om3# om test/sec/plakar key decode --name policy
policies:
    daily:
        periods:
            day:
                cap: 2

root@dev4n1:~/dev/om3# om test/sec/plakar key decode --name passphrase
