* In 2.0.0.x become was reversed for synchronize. It was happening on
the local machine instead of the remote machine. This restores the
ansible-1.9.x behaviour of doing become on the remote machine.
However, there's aspects of this that are hacky (no hackier than
ansible-1.9 but not using 2.0 features). The big problem is that it
does not understand any become method except sudo. I'm willing to use
a partial fix now because we don't want people to get used to the
reversed semantics in their playbooks.
* synchronize copying to the wrong host when inventory_hostname is
localhost
* Fix problem with unicode arguments (first seen as a bug on synchronize)
Fixes#14041Fixes#13825
* Fix the task_vars parameter to not default to a mutable type (dict)
* Implement invocation in the base class's run() method have each action
module call the run() method's implemention in the base class.
* Return values from the action plugins' run() method takes the return
value from the base class run() method into account so that invocation
makes its way to the output.
Fixes#12869
* Better comments
* Reorganize code so related settings are close to each other
* Add ::1 to the "localhost" patterns we look for
* Make the dest_port parameter override the ansible_ssh_port setting
* Fix dest_port (wasn't being set)
* more complete detection of delegate_to
* Fix set_remote_user (wasn't being looked for in parameters)
* Instead of removing mode here, have the ansible module accept it
(better documents the parameters doing it htat way)
Also making PlayContext a child class of the Playbook Base class,
which gives it access to all of the FieldAttribute code to ensure
field values are correctly typed after post_validation
Fixes#11381
