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

Improvements to the rax inventory script
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.
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")
Merge pull request #6754 from ahtik/fix-ufw-take2

Bugfix to ufw module to properly support "logging" (and docfix for choises, choices):
backreferences should be double escaped
Fix YAML docstring that broke webdocs
Merge branch 'devel' of https://github.com/dstokes/ansible into dstokes-devel
More descriptive error message if init system is unknown
Removing wait loop around initial state check during registration

Also fixed a bug in which the state parameter was marked as a 'bool'
type, which was breaking execution of the module.

Fixes #6543
