the class SSHLauncher method setupKey.

/**
 * Setting up the key involves the following steps:
 * -If a key exists and we can connect using the key, do nothing.
 * -Generate a key pair if there isn't one
 * -Connect to remote host using password auth and do the following:
 *  1. create .ssh directory if it doesn't exist
 *  2. copy over the key as key.tmp
 *  3. Append the key to authorized_keys file
 *  4. Remove the temporary key file key.tmp
 *  5. Fix permissions for home, .ssh and authorized_keys
 * @param node        - remote host
 * @param pubKeyFile  - .pub file
 * @param generateKey - flag to indicate if key needs to be generated or not
 * @param passwd      - ssh user password
 * @throws IOException
 * @throws InterruptedException
