Description of problem:
Currently when attempting to update certs on RHUA your rhui-installer run can fail leaving your RHUI in a bad state.

The reason for failure appears to be due the requirement for certain actions against the shared mount point.

The module at: /usr/share/rhui-installer/modules/rhua/manifests/mounts.pp contains a section:

18   exec { 'set-share-permissions':
19     command => "chown -R apache:apache ${rhua::remote_fs_mountpoint}",
20     path => '/usr/bin/:/bin/',
21     require => [Exec['create-share-dir'], Package['httpd']],
22   }

This chown operation was extremely long running over NFS mount, even though all of the permissions were already set correctly.
This caused an indefinite failure for our installer runs due to a buildup of `chown` operations and slow activity on their part.

To work around the issue, I changed line 19 of the module:

19     command => "echo test", #chown -R apache:apache ${rhua::remote_fs_mountpoint}",

Then killed all of the chown operations in progress:

# pkill chown

I could then successfully run the installer.

Version-Release number of selected component (if applicable):
rhui-installer-3.0.0-1.el7ui.noarch
rhui-installer-base-3.0.0-1.el7ui.noarch

How reproducible:
? (100% in our test env)

Steps to Reproduce:
1. Have a NFS mounted/slow storage environment?
2. Run default rhui-installer

Actual results:
If chown operation does not complete/hangs, installer will fail.

Expected results:
The chown operation against
