3363.9 warden stemcell fixes the problem.

3363 and 3363.1 warden stemcells that were published recently have an
agent that did not account for newer stemcell security settings (locks down
ssh access only to bosh_sshers group users). upcoming 3363.5 stemcell will
resolve this problem.
sorry for inconvenience,
