message: [cluster-test] Install awscli
  One of previous commits removed installing awscli from cluster-test runner.
  We need it actually, so putting it back
  Since we have single ec2_user_data.sh for all instances, this will mean installing awscli on all hosts, which should not be big deal(it was there before)
