On Red Hat, CentOS and Fedora systems, the pip binary will be called python-pip
instead of pip. This commit makes the pip module also check for python-pip.

The reason we check for python-pip *first*, is to have ansible fail on not
finding 'pip' and reporting *that*. This is consistent with current behaviour
and will not confuse users of Debian et al., where the 'python-pip' binary
never exists.

Tested on Fedora 18 and Ubuntu 12.04.

The pause 'prompt' parameter now requires quotes around the message.

Check rc instead of parsing for errors.  

Miscellaneous fixes to module_formatter.py

implement lookup plugins for arbitrary enumeration over arbitrary things.   See the mailing list for some cool examples.

Try to autodetect MODULEDIR, instead of hardcoded path in jpmens
homedir.
Check if MODULEDIR exists; exit if it doesn't.
Rewrite boilerplate() to use DOCUMENTATION.yaml in examples/.  This
makes use of tbielawa's recent change that added this example file.
This also fixes -G so that it works.  boilerplate() was commented out
before.

#1303: add sudo option to tasks

Check rc instead of parsing for errors.  This now catches the case where the remote branch has been deleted and you're still trying to pull against it.

This commit improves the following items:
 - Remove the 'match' functionality, this can now be achieve by using the `fail` module together with `only_if` after running the `hpilo_facts` module. Since this gives more functionality, e.g. comparing server names, but also serial numbers or uuids with other inventory information, this is prefered. An example is added to show how this is achieved.
 - Clean up all C() calls in documentation
 - Added state=poweroff in order to power off a server. The use-case is here that in general we do not want to provision systems that are already running (this enforcement can be disabled using force=yes) but for test systems we should be able to power them off so we can start the normal provisioning process. (We could also force boot them, but that's less elegant)
 - The module now correctly indicates when something has changed. So if a server is powered off that was not off already, this is indicated, or when media boot-settings have been changed, this is also correctly indicated. Previously every call to hpilo_boot was (incorrectly) considered a change.

This commit improves the following items:
 - Clean up all C() calls in documentation
 - Reindent the documentation
