Jesse Pretorius 8c80ed8848 Only test for repo availability once
The tasks to test for the availability of the repo,
package cache, etc only need to be done on a single
host - and the facts only need to be set by a single
host. From there on, all hosts will have access to
the facts.

This should save a significant amount of time on
large clusters.
