Foreman Maintain

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1652516

Description of problem:
Foreman Maintain backups up the entire /var/www/html/pub directory during "Collecting Config files"

If the customer has placed other things in this pub directory - they are also backed up. I noticed this when the script had been stick on "Collecting Config files" for over 15 mins and the config_files.tar.gz was at 26G

Version-Release number of selected component (if applicable):
rubygem-foreman_maintain-0.2.11

How reproducible:
100%

Steps to Reproduce:
1. Place some large files in /var/www/hml/pub
2. run foreman-maintain backup
3. observe the entire contents of pub dir get added to the zip file

Actual results:
a config_files.tar.gz that is 30G in size

Expected results:
a config_files.tar.gz that is less than 300M
