Revert "opera adapter fix2"

* opera_adapter need sshpass which may cause deploy
fail
* compass log redirection is the last command which
always return 0 and thus cover deploy error

1. add installation of sshpass in prepare.sh
2. echo a string at the end of deploy/launch.sh into
log file to judge if deployment is complete
3. fix typing error in util/check_valid.py
