Multi realm installs - Allow for modification of enabled realms…

[tpetrus]

Integrate selection of desired realms to be enabled in XDMoD instance and allow all tests to pass based on which realms are enabled.

Description

• Environment variable XDMOD_REALMS now used to set desired realms in a comma-separated string style
• Modified bootstrap among other files to only ingest proper items required for the realms desired
• Made Job Viewer tab disabled if the jobs realm isn't enabled, and suppressed error messages corresponding to JobViewer not finding the jobs realm (if it's not enabled)
• Updated all tests to properly work with whatever combination of realms that are enabled (This included splitting up the proper test artifacts by realm)

Motivation and Context

It allows for the selection of realms to be enabled, where before there was no way to do so.

Tests performed

I ran all tests on every single combination (and order) of Jobs, Cloud, and Storage realms possible, using both the fresh_install and upgrade test modes, and all on fresh XDMoD instances.

I ran the same script commands that Shippable currently runs to do its tests of XDMoD. This included setting up a new XDMoD instance with the desired realms, and running regression, integration, component, UI, and all SSO tests on that instance.
