Add forgotten 'Restart container' handler for swift

Since I0474324b60a5f792ef5210ab336639edf7a8cd9e swift role uses the new
service-cert-copy role introduced in the
I6351147ddaff8b2ae629179a9bc3bae2ebac9519 but the swift role itself
doesn't contain the handler used in the service-cert-copy. Right now,
restarting the swift container isn't necessary, but the handler should
exist. Also we should fix the name of the service used.
