AMI 1.0.4-1 - ssh connection refused error occurred for newly created instance

Build tested: 1.0.4-1AMI

For AWS installatoin for a 1UM2PM configuration, postConfigure creates the instances for UM1 and PM2, then continue on connecting to the two instances for further installation. At the time of connection, sshd seems to be not yet ready and a “connection refused” occurred. Installation failed. I reran postConfigure (this time, with the instances up and running already), installation was successful. I think we need to account for the fact that sshd will take time to come up on a new instances.
