Fix EasyEngine cron behavior to support proper Linux Cron like behavior

For now we need to throw warnings for `;` and `#` symbols as they're not supported in Ofelia.

I'm looking at the [Ofelia](https://github.com/mcuadros/ofelia) code. They're using the [gcfg.v1](https://github.com/mcuadros/ofelia/blob/master/cli/config.go#L10) for reading the config file. Need look into possible replacements.
