(maint) Add ext/packaging to .gitignore
(maint) Don't require mcollective for all tasks

Because the test task is defined using an RSpec object, if rspec is installed,
many other libraries will also be loaded, which will cause failures on builders
trying to use the rake tasks. This commit lessens the risk by trying to load
mcollective, and rescuing the load error. If mcollective successfully loaded,
we continue to try to load the other libraries. This could still fail, but
failure is less likely. Really, the test task definition needs to be completely
reworked.
(maint) Add packaging tasks and hooks

This commit adds standard packaging tools and hooks to load those tools.
(maint) Add packaging data files

This commit adds the data files that drive packaging to ext. This includes
project_data.yaml and build_defaults.yaml.
(maint) Add packaging artifacts for debian and redhat

This commit adds packaging artifacts for debian and redhat. This will allow the
plugin to be built using our standard toolset. The artifacts have been written
so that the packages behave equally to the currently produced
mcollective-pluginpackager packages.
