Let PowerState class run multiple callbacks

Previously the PowerState class could only handle a single callback
function. This commit changes that to allow other callback functions to
be added with a addCallback() method. The callback functions are then
executed when the power state changes.

This also changes the use of the PowerState object in the fan presence
code to a shared_ptr instead of a unique_ptr, and adds a function to
return the PowerState object to use in the app, creating it if
necessary. This allows multiple pieces of the code to add their own
callbacks to the same object.

presence: Make error time be per fan

Previously there was a global value for the amount of time a fan needed
to be missing before an event log was created. This commit changes it
so that instead the value is specified per fan in the JSON.

This way, the times can be different or left off completely on a fan to
fan basis. The ErrorReporter object will only be created if there is at
least one fan with a time value.

presence: Create event logs for missing fans

After the fan missing timer expires, create an OpenBMC event log with
the name xyz.openbmc_project.Fan.Error.Missing. It will call out the
fan using the CALLOUT_INVENTORY_PATH AdditionalData keyword.

It will also add the Logger output in JSON as FFDC by saving it in a
file and passing in that file's descriptor as the event log API
dictates.

presence: Track missing fans with timers

Fill in the ErrorReporter class to track fan presence status using Timer
objects. The timers will be started if power is on when fans are
removed. If a fan is replaced before the timer expires, or if the
system powers off before the timer expires, the timer will be stopped.

The function called when a timer expires is currently stubbed, but
eventually it will create an event log.

The class watches presence changes by watching the Present property for
the fans in the inventory. Technically, it could watch an internal
status, but this method was chosen because
a) It makes testing easier, so presence changes can be forced using
busctl as opposed to physically removing hardware.
b) There wasn't really a good place to hook in presence state watches.
c) The application would already crash anyway if the inventory service
wasn't working for some reason.

presence: Create ErrorReporter class

This class will, eventually, create event logs for missing fans.

This first commit will just create a stubbed out class if there is a
'reporting' section in the configuration JSON. From the JSON, the class
will pull out the value for the number of seconds to wait between first
detecting a fan is missing and creating the event log for it.

This requires a slight change to the existing JSON format, however the
JsonConfig class was updated to support both the old and new formats.
