Text field for job name

The "testjob" is when you select a bunch of tests to run, and you run
them (maybe once, maybe multiple times in soak). This is in contrast to
a "testrun" which is a single run of a single test.

This "testjob name" is the directory name where the results will be
stored. Strictly speaking, it should be "results name" or "report name"
or something like that, because you can run 2 or more testjobs and have
the results combine into a single report (that is, stored under the same
directory).
