Add crawlers in serverless config

[aline-tg]

Hello toryas!
First of all, thank you very much for this development. It is really helpful to us :)

I have a question:
It's not clear in documentation if it's possible to add crawlers for a specific Glue Job.
Can we do this using the triggers ? Or using something else on serverless-glue plugin?
From my research, we are able to start a crawler on triggers but not to create a new one using this.

For crawlers creation, I have been using the "glc-data-glue-crawlers-serverless-plugin".
I think it's cool to have something similar with this plugin on serverless-glue.

Take this into account in your future updates. :)
