Add solid-power, a small tool to query power stuff

Small tool that will be able to report anything related (and supported)
to power using Solid::Power.

At the moment it only implements Show which reports wether the ac is
plugged or not.

TODO for the tool is:
-Listen to events
-Implement all other commands.
