Subject: Adding halo-enable option

Summary:
- Master option for halo geo-replication
- Added prove test for halo mode
- Updated options do values which should work "out of the box" for most use-cases, just run "enable" halo mode and you are done, the options can be tweaked as needed from there.

Test Plan:
- Enabled option, verified halo works, disabled option verified async
  behavior is disabled
- Ran "prove -v tests/basic/halo.t" -> https://phabricator.fb.com/P12074204
