Unify the local and global view for ./bin/phd status.

Browse source 
Summary:
Ref T4209. Unifies the local (`./bin/phd status`) and global (`./bin/phd status --all`) view into a single table. This generally makes it easy to administer daemons running across multiple hosts.

Depends on D9606.

Test Plan:
```
> sudo ./bin/phd status
ID Host      PID  Started                 Daemon                               Arguments
38 localhost 2282 Jun 18 2014, 7:52:56 AM PhabricatorRepositoryPullLocalDaemon
39 localhost 2289 Jun 18 2014, 7:52:57 AM PhabricatorGarbageCollectorDaemon
40 localhost 2294 Jun 18 2014, 7:52:57 AM PhabricatorTaskmasterDaemon
41 localhost 2314 Jun 18 2014, 7:52:58 AM PhabricatorTaskmasterDaemon
42 localhost 2319 Jun 18 2014, 7:52:59 AM PhabricatorTaskmasterDaemon
43 localhost 2328 Jun 18 2014, 7:53:00 AM PhabricatorTaskmasterDaemon
44 localhost 2354 Jun 18 2014, 7:53:08 AM PhabricatorRepositoryPullLocalDaemon X --not Y
```
