1009429 - Move pulp_manage_puppet bool 2 celery_t.

https://bugzilla.redhat.com/show_bug.cgi?id=1009429
Maybe add a second line that the puppet_etc_t labels are applied to /etc/puppet/*

I can also understand if this is redundant because you can look in the pulp-celery.te file. Maybe we could document to refer to that for the location where these labels are applied.
