Run and add ssh key to agent

[unkcpz]

fixes #4

[unkcpz]

If you test with latest full-stack docker image, after generating the key pairs and the ssh-add runs to add to agent. You may still not able to see the key added with ssh-add -l when you open a new terminal app. The reason is there are two ssh-agent running. This is another thing we need to address by aiidalab/aiidalab-docker-stack#409. Only one ssh-agent will run on the session and as mentioned by @danielhollas, it may not be a good idea to put script in .bashrc.
But for this PR, I think it is ready, if you make sure there is only one ssh-agent, after generating the keys, you can find it also added to the agent.

I don't understand. How is it possible that two ssh-agents are running? I thought that the script that we use should ensure that only one ssh-agent is running.

I have no idea, to be honest. The good thing is I can reproduce it with full-stack. Let's try to merge aiidalab/aiidalab-docker-stack#409 first and see if the problem disappears. At least, I think your change there makes things more clear. Hope we can find the problem if it is still exist.

This is tested with the newly released docker stack (I use ghcr.io/aiidalab/qe:edge) and the key is successfully added to ssh-agent.
@yakutovicha Can you have a look and test it? After this change, the computational resource widget can work with this mfa-cscs seamlessly.

Sorry, @unkcpz, I am on it now.

I tested things locally, it is all good 👍

Cool, thanks! Then I'll prepare a release and put the app on the app store, is that okay for you?
