relative pathing comes in handy on occasion, particularly when
delegating to localhost and running some command out of your playbook
repo. Making use of os.path.abspath will allow for the full path to
chdir and executable to be discovered if not provided.

The 'always_run' task clause allows one to execute a task even in
check mode.

While here implement Runner.noop_on_check() to check if a runner
really should execute its task, with respect to check mode option
and 'always_run' clause.

Also add the optional 'jinja2' argument to check_conditional() :
it allows to give this function a jinja2 expression without exposing
the 'jinja2_compare' implementation mechanism.
