Update Interval when timeRemaining is updated

A typical watchdog implementation would give these 2 features:
- Setting the interval
- Resetting the timer which also means poke

This watchdog implementation does not provide a poke function
and the same can be achieved by clients making these dbus calls
in that order.

1) Get the Last set Interval
2) Set TimeRemaining field to result from #1

To achieve #1, this commit adds the support.

This would make sure that the new timer would expire after last
updated user interval from that time.

Fixes openbmc/openbmc#767

Typically sd_event* calls can not go wrong and if they do, better
would be to terminate the application so we get a coredump.

Invoke optional callback function on timer expiration

When the timer expires, it calls into it's own timeout
handler which matches with sd_event callback handler.

However, it is beneficial if the users of timer register
their own callback routine so that they can execute some
operations on timeout.
