Convert the Patching guide (https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.3/html/patching_and_upgrading_guide/index) to follow modular guidelines

Exit Checklist:

[ ] Evaluate EAP guide titles: 

Evaluate all of the EAP documentation guide titles and consider renaming to be more consistent with each other. Specifically:

1. The security guides that start with "How To..."
2. The guides with JBoss EAP in the title - some spell out the whole product name, others use the shortened version.

[ ]Use non-breakable space between the product name and its version in eap-release-notes, server-migration-tools and eap-openshift repos

[ ] Limit heading levels to 3.  There should not be any headings deeper than 3 levels. 

[ ] Add chapter about leaving feedback to all guides
