Tristan de Cacqueray 1e0af6779b Add remove-zuul-sshkey
This change enables a kubectl connection job to just remove the
zuul sshkey, without using the add-build-sshkey role which doesn't
work on pod. To do that, this change moves the sshagent_remove_key
task to a new role and makes add-build-sshkey use the new role.
