Adds the given job to the job list and wakes up the scheduler if it's already running.
Any option that defaults to ``undefined`` will be replaced with the corresponding default value when the job is
scheduled (which happens when the scheduler is started, or immediately if the scheduler is already running).
The ``func`` argument can be given either as a callable object or a textual reference in the
``package.module:some.object`` format, where the first half (separated by ``:``) is an importable module and the
second half is a reference to the callable object, relative to the module.
The ``trigger`` argument can either be:
#. the alias name of the trigger (e.g. ``date``, ``interval`` or ``cron``), in which case any extra keyword
arguments to this method are passed on to the trigger's constructor
#. an instance of a trigger class
:param func: callable (or a textual reference to one) to run at the given time
:param str|apscheduler.triggers.base.BaseTrigger trigger: trigger that determines when ``func`` is called
:param list|tuple args: list of positional arguments to call func with
:param dict kwargs: dict of keyword arguments to call func with
:param str|unicode id: explicit identifier for the job (for modifying it later)
:param str|unicode name: textual description of the job
:param int misfire_grace_time: seconds after the designated run time that the job is still allowed to be run
:param bool coalesce: run once instead of many times if the scheduler determines that the job should be run more
than once in succession
:param int max_instances: maximum number of concurrently running instances allowed for this job
:param datetime next_run_time: when to first run the job, regardless of the trigger (pass ``None`` to add the
job as paused)
:param str|unicode jobstore: alias of the job store to store the job in
:param str|unicode executor: alias of the executor to run the job with
:param bool replace_existing: ``True`` to replace an existing job with the same ``id`` (but retain the
number of runs from the existing one)
