JobQueueCluster: pass security along

[bfis]

JobQueueCluster.__init__ needs to pass the security argument to it's super's (SpecCluster) __init__ since it is needed there too.

Thanks for your PR!

I have noticed that recently too. I have some ongoing branch with a broader scope trying to tackle #386 and fixing some quirks while doing that. Edit: I ended up opening a WIP PR #398

It may take a week before I manage to clean it up a bit and add tests though, plus maybe one week of review.

Here are a few of the options that you have available:

• you manage to extract the Security fix from my branch and add them to this PR with some tests. You can see that you need to do a bit more than adding the paramater.
• if you have some spare bandwidth fixing protocol as well would be very welcome (probably a bit easier than adding security)
• you help me on my branch by doing PRs on my branch, for example by testing it on your cluster and/or adding more tests

By the way if you have a use case for using security in a HPC context I would be quite interested to hear more about it!
