Try reduce groovy-all dependencies

[lucasponce]

Hi @jsanda, I see that cassalog pulls the groovy-all artifact which is the bigger one of all used in metrics/alerting (7Mb).
Do you know if that dependency could be reduced with individual dependencies with some core features ?
It is not urgent, for next Sprint of Alerting I am studying how to simplify big dependencies and I was wondering about this one.
Thanks !

I changed the dependency from groovy-all to groovy which is 2 MB. That's still pretty big but a lot smaller than groovy-all. I did a smoke test with installing HAM.
