Enhancement: Add custom test naming

[jjo93sa]

It would be handy to be able to (pre/ap)pend a string to the names used for the CaaS test appliances to and more entropy. Currently they have a format:

test-bb36z

We'd like to be able to add to the name so it becomes:

additionaltext-test-bb36z
or
test-bb36z-additionaltext

This would support determination if the test was being run automatically, or if it was being executed by a user.
