Fix Idempotence issue for RHEL 7 forwarder install

[TraGicCode]

I could really use a second pair of 👀 on this. I was sifting through the issues on github for this module and noticed someone having a problem a RHEL 7. While i was not able to reproduce their issue specifically ( i assume it's fixed ) i did notice the idempotence test for the forwarder is failing when run under beaker. I know pretty much nothing about se_linux on RHEL 7 but what i do know is the following attribute on the file resource solves the forwarder idempotence test. Could anyone verify this fix is indeed valid?

FYI. Here is the failing beaker test without this change.

mh I've no idea. @vinzent @oranenj can you help us out here?

[oranenj]

Hard to tell what's going on without actually testing the module myself, but my initial guess is that something changes the SELinux policy while puppet is running (eg. one of the packages it installs) so that on the next run, the file contexts for that particular path are different than on the first run and puppet corrects them.

To see which is "correct", run restorecon on that path. If it changes from unconfined_u to system_u, then that's what the policy declares and the puppet code should probably default to that too.

[wyardley]

I'm also not sure, but what @oranenj says makes sense (if the settings are coming from the package rather than from Puppet, you could also try looking at the rpm's scripts).

[TraGicCode]

I'll give this a shot.
