Improve error messages from running commands

[danielsuguimoto]

We have a few known errors/situations where the output error from the final command being executed becomes misleading since the user is calling kool only. So we need to come up with some parsing for error outputs, so we can intercept and improve/make clear the error and what do to for the user.

KOOL_APP_PORT=8080 KOOL_DATABASE_PORT=13306
