1.Prepare KMS with aws command

rosa create cluster --cluster-name ying-k1 --sts --role-arn arn:aws:iam::301721915996:role/ying16-Installer-Role --support-role-arn arn:aws:iam::301721915996:role/ying16-Support-Role --controlplane-iam-role arn:aws:iam::301721915996:role/ying16-ControlPlane-Role --worker-iam-role arn:aws:iam::301721915996:role/ying16-Worker-Role --operator-roles-prefix ying-k1-e2g3 --oidc-config-id 23ggvdh2jouranue87r5ujskp8hctisn --region us-west-2 --version 4.12.15 --replicas 2 --compute-machine-type m5.xlarge --machine-cidr 10.0.0.0/16 --service-cidr 172.30.0.0/16 --pod-cidr 10.128.0.0/14 --host-prefix 23 --kms-key-arn arn:aws:kms:us-west-2:301721915996:key/c60b5a31-1a5c-4d73-93ee-67586d0eb90d 

It is failed. Here is the install log 
http://pastebin.test.redhat.com/1100008

There should be a detailed error message for the KMS that has no installer role 

It can be successful if set install role arn to KMS key
