Added support for watch and callback on 'interface added'
signal for the specified object paths.
Added mako scripts for events to auto create callback
and watch objects for the specified object path groups.
Clients specify object paths to watch and callbacks to
invoke in the config.yaml file

This callback class will create an error log with
exactly 1 metadata field, which takes a string. This
metadata field will be filled in with the property paths,
names, and values of the properties that passed the
condition checks that caused the callback to be called
in the first place.
Tested: Ran with YAML rules that used this callback and
checked that everything worked as specified.

When a count condition is a oneshot, it will only
trigger the callback the first time the condition
is true. The condition needs to evaluate to false
at least once to rearm the callback.
A use case for this would be when a group of properties
is being watched for a subset of them hit a certain value.
Even though every properties changed signal for every property
in the group would check the condition, only the first time
the condition is true would the callback be issued.
This behavior is specified with a 'oneshot: true' entry in
the YAML. If not present, it defaults to false which is
the original behavior.
Tested: Verify this does indeed do what is advertised by
modifying condition rules to consistently pass
and checking behavior.

eg:-
- name: example event callback
description: >
'Callbacks are actions PDM should take when instructed to do so.
Some callback types refer to a group of paths and group of properties
in a similar fashion as the property watch directive.
The event callback creates the event D-Bus object with the given name
and the event message.
eg /xyz/openbmc_project/events/test/<id>'
class: callback
callback: event
paths: example path group
properties: example property group
eventName: test
eventMessage: "Test configuration changed."
When fully implemented, event callbacks will create DBus objects for
preconfigured DBus events.

journald ignores lowercase metadata keys so require them
to be uppercase. Abort the config file parse when lowercase
keys are found.

Deferrable callbacks delay callback invocation until a
pre configured length of time has elapsed. One example
scenario where deferrable callbacks help is to avoid
oscillation when testing a condition and making callbacks
frequently.

Add support for a method callback. The method callback enables
arbitrary DBus method calls. A sample use case could be
starting a systemd unit via the sytemd DBus API.

Callbacks must ultimately be triggered when a property
is updated by a watch. Add that support.

Callbacks are the response in the PDM 'trigger->response' model.
Add general support for implementing callbacks and implement
a log to systemd journal using that framework.

Add support for defining groups of DBus properties. Groups are
a list of property/interface/metadata tuples. Metadata can be used to
