Still compatible with user: but deprecating it so we can have
a matching remote_user: in tasks, cannot be user: because of the
module of the same name. #3932

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.
Tests `test_playbook_undefined_varsX_fail` check if ansible detects
undefined variables when `error_on_undefined_vars` is enabled. These
tests fail without "Improve behavior with error_on_undefined_vars
enabled" patch.
Tests `test_playbook_undefined_varsX_ignore` check if ansible ignores
undefined variables when `error_on_undefined_vars` is disabled.
Also modify PlayBook._run_task_internal() so error_on_undefined_vars is
testable.
ansible.constants was calling expanduser (by way of shell_expand_path)
on the entire configured value for the library and *_plugins
configuration values, but these values have always been interpreted as
multiple directories separated by os.pathsep. Thus, if you supplied
multiple directories for one of these values, typically only the first
(at least on *nix) would have e.g. "~" expanded to HOME.
Now PluginLoader does expansion on each individual path in each of
these variables.
If someone has a " #" in a quoted var string, it
will interpret that as a comment and refuse to
load the inventory file due to an unbalanced
quote. Noisy failure > unexpected behavior.
PluginLoader._get_paths, as of 391fb98e, was only finding plug-ins that
were in a subdirectory of one of the basedirs (i.e. in a category
directory). For example, action_plugins/foo.py would never be loaded,
but action_plugins/bar/foo.py would work.
This makes it so that "uncategorized" plug-ins in the top level of a
directory such as action_plugins will be loaded, though plug-ins in a
"category" subdirectory will still be preferred. For example,
action_plugins/bar/foo.py would be preferred over action_plugins/foo.py.
