Description of problem: Add documentation about how to let system administrators add a message on the RHV welcome page using a small custom branding with a preamble section. The initial request for the feature is BZ1804774. An example brand is attached to that BZ (https://bugzilla.redhat.com/attachment.cgi?id=1783329). A few examples where this feature can be useful: - communicate planned maintenance of the infrastructure - quickly add some company logo image (but a full portal branding would be nicer [1])) It is also important to note that after setting up a custom brand, an engine restart is needed in order to make the change active.

@sdickers please include a link to the RHV welcome page where you want to add branding.
Here is a RHV welcome page screen shot with a generic preamble branding added: https://bugzilla.redhat.com/attachment.cgi?id=1783328 The preamble section is the white box.
