Extend storage array to contain additional data

This array was originally just an array of objects of
type 'any'. This commit changes it to be an array of
tuples of type <any, any> to add an extra field for
use by anything that needs it.

For example, the storage is currently used to store
property values, and a future change to the CountCondition
class will now also store the result of the comparisons done
between the property values and another value specified in
the rule YAML. Then, a callback will be able to see the
result of whether each property passed the check.

Add oneshot support to count conditions

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.

to have logic around the conditions they were invoked in.

There are two context on which call back can be invoked
1) Startup: during startup all the call backs will be called
2) Signal: As part of condition match on the watched properties.

Callback would behave differently based on the context.
eg: eventCallback
1) Startup: Don't take any action.
2) Signal: Create the Dbus Object for the event.

Adding the section for event call back.

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.
