power-recovery: introduce CurrentPowerStatus to chassis

The power coming into a chassis can have its own status. For example, if
power has been lost (blackout) but the system has an uninterruptible
power supply(UPS) connected, then chassis power could still be on but
its important to provide the fact that the system is running off of a
UPS to other BMC software.

For example, IBM has a policy that it will allow a system to remain on
if it is already on when a blackout or brownout occurs (and running on
a UPS), but it will not allow a user to power a system on if in one of
these conditions. IBM will also not allow a system to power on until
a UPS is fully charged.

The design for this can be found over in the following series:
