Update path_dwim() to return absolute path

If path_dwim() is provided a relative path to a file, it will now return an
absolute path of the playbook directory + the relative file path.

Make script module use raw module so it does not require python

[docsite] Added LEMP selected playbook

Add return code and error output to raw module

Since we use 'raw' heavily on equipment where 'command' and 'shell' are not (yet) working (and python may need to be installed first using raw) these improvements are necessary in order to write more complex scripts (with return code handling and separated stdout/stderr).

This change includes the following changes:

 - exec_command() now returns the return code of the command
 - _low_level_exec_command() now returns a dict, including 'rc', 'stdout' and 'stderr'
 - all users of the above interfaces have been improved to make use of the above changes
 - all connection plugins have been modified to return rc and stderr
 - fix the newline problem (stdout and stderr would have excess newlines)

In a future commit I intend to add assertions or error handling code to verify the return code in those places where it wasn't done. Since only the output was available, the return code was ignored, even though we expect them to be 0.

Make all lookup plugins accept lists as arguments

Alphabetic inventory hostname patterns.

of hash iteration.

Allow parameterized playbook includes to define complex variables

To be used like:
- include: playbook.yml
  vars:
    mylistvar:
    - item1
    - item2

Lookup plugins should accept a string or a list, and always return
a list, even if it is just one item.

Change message when a play matches no hosts

change error message on check_conditional when variable does not exist

Make use of yes/no booleans in playbooks
