Description of problem:

The manual job [1] has:

ENGINE_VERSION: drop down that lets you pick 4.1, 4.2 or master

Below that, a text table that does not mention 4.2 at all, and says that choosing engine '4.1' and then 'upgrade-from-release' will update _from_ master to 4.1.

SUITE_TYPE: drop down that includes "upgrade from release" and "upgrade from prev release".

It's not clear what the current options are.

Do we want to test upgrade-from-prevrelease at all? Current 4.1 and 4.2 prevent that (i.e. upgrade from 3.6 and 4.0, respectively). master (4.3) still allows upgrade from 4.1, but mainly because no-one yet pushed a patch to prevent that - there are no plans that I know of to allow that officially.

So, perhaps:

- Drop prevrelease altogether

- Allow only these upgrades:
4.0->4.1 (or just remove 4.1)
4.1->4.2
4.2->master

- Drop the table, or fix it to say the above
