pytools: obmcutil: Implement verbose mode

Verbose output is limited to state change requests at the moment, as
they are the operations that take significant amounts of time. Further,
the verbose output is implemented as following the tail of the journal
until the requested state change either succeeds or fails.

In testing it was observed that the journal output tends to lag the
DBus event that signals the completion of the state transition. As such
the patch adds a tuning parameter defining a further waiting period
beyond the receipt of the completion signal so that the verbose output
looks "reasonable". The default value of the tuning parameter was
roughly chosen to correlate well with the journal output on a
Witherspoon system for the `poweron` command.
