* enable batch mode (configurable with a config option, on by default)
for sftp transfers, so we can catch errors more easily
* general cleanup in the local connection plugin and fetch action plugin
Fixes#11612
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
Moving the make_sudo_cmd() calls back up to the action level so that connection
plugins don't have to know about it at all, and moving some of the become data
(prompt and success_key) into the ConnectionInformation object so they don't
need to be passed around needlessly.
- moved check prompt/password functions to connection, make more senes there
- TODO: consider moving make_become to connection from connection_info
- removed executable param that was never overriden outside of connection info
