Parse I2C bus and address out of JSON config file

The I2C bus and address need to be passed down to the PowerSupply
constructor, so get those out of the JSON configuration file now.

Change I2C address format in JSON to be a string, without the
hexadecimal format since it needs to be appended to a string, allowing
to skip conversion from string to number and then from number back to
string.

psu: Updates for power supply presence

Update the JSON file to indicate the minimum and maximum number of power
supplies this system can have.

Update the JSON file to have an array of power supply objects, each with
their various own properties. Each power supply will have:
1) An associated D-Bus path for the inventory. This will have the
Present property.
2) An associated I2C bus number.
3) An associated I2C bus adddress.

Update PowerSupply class to have a present member variable, an
isPresent() accessor function, and two functions for updating the
presence. One function will be the call back function for either
inventory change events or interface added events, which will use
associated match member variables. The second function being one that
attempts to read the inventory Present property on startup. If reading
the Present property on startup fails, the property changed or interface
added events should work to get the value when that property is
available.
