Bug 1207304

We'd like to ease the use of the default scap-security-guide xml files. 
The scenario is: 
scap-security-guide xml files are on the client host.
A user creates policies on Foreman. The policies' data is synced via puppet to the client host.
The user does not need to copy / move scap-security-guide xml files to /var/lib/openscap/content/<digest>.xml

On Client host side
# Add scap-security-guide as an RPM dependency to foreman_scap_client RPM
# Post install creates a symlink between the security guide xmls to /var/lib/openscap/content/<digest>.xml:
## Extract scap-security-guide xml digest
## symlink scap-security-guide xml to /var/lib/openscap/content/<digest>.xml

On foreman_openscap
# Add scap-security-guide as an RPM dependency to rubygem-foreman_openscap RPM
# A seed which automatically creates a Scaptimony::ScapContent with the contents of the scap-security-guide
