Module for managing nodes in a Rackspace Cloud Load Balancer
use lgetfilecon_raw instead of lgetfilecon to not depend on local level translation

If SELinux is enabled and mcstrans is running, daemons are restarted on each
run. After further debugging, it turn out that ansible compare the untranslated
level 's0' with the translated level 'SystemLow' due to mcstrans being running,
which trigger a handler since this is considered as a change.

add a way for callback to disable itself

The idea is that some plugin would not be called in some
specific case, and the callback should decide by itself.

Having a way to globally disable it is much cleaner than
disabling every method one by one on the plugin side.

My use case is for fedora-infrastructure that cannot be run
from git checkout since it try to connect to the message bus,
but another case would be to bootstrap infrastructure, or to
run the code on a test servers without having all the callback
infrastructure setup.
Fixed usage comment to fish syntax for sourcing a file
add test for the disabling of callback plugins
added version checking, doesn't work in older versions
- fixed typos and errors from feedback
