Description of problem:
Puppet class correctly creates an entry in the root crontab but, if the compliance policy is deleted, the entry is not being removed:


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

# cat /usr/share/puppet/modules/foreman_scap_client/metadata.json 
{
  "name": "isimluk-foreman_scap_client",
  "version": "0.3.6",
  "author": "isimluk",
