Add option "deployment size" to tune system properly
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1215390
Description of problem:
Various default values (, , ) limit Satellite6 usage to various maximal number of content hosts. A user has to manually tune the system when wanting more content hosts.
As many Satellite deployments are supposed to hit either of the limit, the tuning is required for most deployments. It can be written down in manuals (see bz1159281) or even better done automatically by installer to:
- simplify the manual steps during installation
- prevent (resolving) customer issues when not following that recommendations
Therefore I suggest having an option reflecting deployment size (in # of content hosts) that will update the settings. Alternativelly, the installer can set the parameters everytime to some safely high values (i.e. for 10k content hosts or so).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run katello-installer in either way.
parameters mentioned in bz1159281#c0, bz1159281#c4 and bz1159281#c12 have default values.
Have possibility to fine tune the values for larger deployments automatically.
