TL;DR: I just updated Jenkins and its plugins. If things stop working
correctly, please let me know.

Some details below, in case I'm not here when things start to break down...

I updated Jenkins and its plugins to the latest versions, hoping to fix the
problem we've been having lately where we would only ever get a single EC2

The result was an AWS EC2 plugin that started many, many EC2 slaves, but on
the Jenkins side mapped all slaves to the same URL, which resulted in
multiple builds running concurrently on the same EC2 instance, which
obviously resulted in many failures.

I rolled back the AWS EC2 plugin from 1.42 to 1.39 (like I had to do a few
weeks ago), and things to be back to normal. It even works better than
before I attempted the upgrade: the plugin correctly spawns multiple slaves
as required.

Frankly I don't understand what is going on, but it works again so I'll
stop touching it. I suppose I should take the time to investigate, attempt
to reproduce the problem and report it to the plugin maintainers. I
currently do not have a few days to spare for that, so it'll wait...

For the record, I also had to do the following during the upgrade:

   - I had to update the AWS permissions for the EC2 plugin:
   - I had to install a plugin to ensure running builds are no longer
   allowed to do whatever they want (~root permissions):
