Added an option to be able to choose to manage recursively all the files
in the work dir, on systems with a lot of files probably you want this
to false

Conflicts:
	manifests/init.pp
	manifests/package.pp
	manifests/params.pp
Settle on $nexus_work_recurse
Actually pass nexus_work_recurse to nexus::package
Merge pull request #32 from hubspotdevops/recursion

Make managing ownership and perms on $nexus_work_dir optional.
