Started the development of the 'chdir' functionality for file module - creation symlinks without the base directory prefix
Found a way how to have symlinks towards files without absolute paths in prefixes; fixed incorrect force setting on the hard links, which can not point to non-existing files
Updated the force parameter description; added one example how to create the symlinks pointing to non-absolute paths

Treat 255 errors from raw as dark host

Any other module is able to detect a dark host, but raw was treating 255
as a return code from the module execution, rather from the connection
attempt. This change allows 255 to be treated as a connection failure
when using the raw module.
Allow you to pass in arbitrary rsync options. I also added help for it, and what version it was added in.
Added template call to _executor_internal to allow the passing of arbitrary data to modules.
Bugfix for ufw to support "logging" properly:
It's a separate parameter so updated docs and set it as mutually exclusive param.
Also due to an array construction typo it was not working in any situation (ufw LOGLEVEL was passed to cmd instead of ufw logging LOGLEVEL).

Also fixed doc and parameters parsing typo ("choises" should be "choices")
