move chassis power services to phosphor-state-manager

Move the generic services which are used to power on and off the chassis
into phosphor-state-manager. This will make the use of
phosphor-state-manager for chassis power control more straightforward.

These services are directly copied from openbmc/openbmc/
meta-phosphor/recipes-phosphor/chassis/obmc-op-control-power/ and
renamed to match with the existing naming conventions.

The only change to these files was if a Wants/Before/After service name
was changing as a part of this.

A follow on commit will improve some of the Description fields.
