Add a --force command to phd start

Browse source 
Summary:
Ref T7352. This isn't wildly useful for us but seems generally reasonable, can be helpful with testing, and @hach-que has a use case for it.

The only reason we issue this warning is to prevent user error; you can still launch all the daemons with `phd launch` manually and daemons all use locks to protect critical regions.

Test Plan: Ran `phd start --force` a bunch, saw zillions of daemons.
