    [BEAM-3013] Prototyping lull-tracking for Python

    r: @charlesccychen 
    cc: @bjchambers 
    This change is to allow the state sampler in Python to report when too much time has been
spent on the same state (default: 5 minutes). When more than 5 minutes have been spent, the
worker will report it.
    This change requires the sampling thread (normally a pure-C thread) to acquire the GIL,
to access the logging module. For this, I laid out a convention to acquire locks in a certain
order - to avoid deadlocks.
