DOCTEAM-1775: HA resources and constraints

[tahliar]

PR creator: Description

At long last, here are the articles for managing resources and constraints. Sorry it's such a big PR; the content was too inter-related to split up.

These aren't the most ideal Smart Docs, but this generic content does need to exist as it's the foundation of how to use the product. I will be doing plenty of focused articles on specific tasks later.

PDFs:

Configuring HA Cluster Resources: HA-resources-configuring_en.pdf

Adding Constraints to HA Cluster Resources: HA-resources-adding-constraints_en.pdf

Managing HA Cluster Resources: HA-resources-managing_en.pdf

Note that the crmsh/Hawk procedures appear one after the other in the PDFs, but in the published HTML they'll look like this:

This was the the smoothest solution I could see for having two methods to do things; having a separate topic for each method would blow out to way too many topics to reasonably keep track of.

Tasks for later:

There was more I still wanted to do, but I can't keep working on one PR forever, so I split some things off for later. If a topic seems to be missing, it might be in this list:

• https://jira.suse.com/browse/DOCTEAM-2203 (manually moving resources)
• https://jira.suse.com/browse/DOCTEAM-2205 (batch changes with hawk and crmsh)
• https://jira.suse.com/browse/DOCTEAM-2033 (placing resources based on their load impact)
• https://jira.suse.com/browse/DOCTEAM-2032 (resource failover and failback nodes)
• https://jira.suse.com/browse/DOCTEAM-2250 (miscellaneous ideas for new content)
