Description of problem:

[RFE] Extend kickstart to allow pause and snapshot after package install


Version-Release number of selected component (if applicable):
Red Hat Satellite v.6.1.8


Issue:

Customer is having a cloud setup and while provisioning of instances in cloud systems, it is becoming more popular to clone from an image. 

As per customers request tt would be a significant benefit to customers to be able to create an image which is half way through the kickstart process (i.e. has installed package list, and perhaps run a handful of security lock-downs in the %post section). This kickstart process would then be shut down to allow the image to be made.

This kickstart process would then be shut down to allow the image to be made.
When creating cloud instances from this image, the first task of the instance would be to contact the provisioning platform (Satellite 6 in our case) and request the rest of the kickstart details to execute (possibly as part of firstboot?).

This would allow images to be created once every point release (i.e. RHEL 6.7, RHEL 7.2 etc), but the resulting cloud instances could be registered to Satellite, Puppetised, UUID's generated etc. and fully patched up by the kickstart remainder.



Additional info:

Upstream plugin to add API to do it within Foreman (openstack and libvirt only) - https://github.com/theforeman/foreman_snapshot might be considered as a part of the feature request.
