Description of problem:

Nigel babu left the admin team as well as Red Hat. We should clean and remove access and document that.

SO far, here is what we have to do:

Access to remove:
- remove from github (group Github-organization-Admins)

- remove ssh keys in ansible
 => done

- remove alias from root on private repo
 => done

- remove alias from group_vars/nagios/admins.yml
 => done

- remove entry from jenkins (on https://build.gluster.org/configureSecurity/)
 => done

- remove from gerrit permission
 => TODO

- remove from gluster repo
   => edit ./MAINTAINERS

- remove from ec2
  => TODO

While on it, there is a few passwords and stuff to rotate:

- rotate the ansible ssh keys
  => done, but we need to write down the process (ideally, a ansible playbook)

- change nagios password
  => TODO

- rotate the jenkins ssh keys
 => TODO, write a process

Maybe more need to be done
