Hello @ivantodorovich
I'm not a big expert in these modules.
Following the issue raised and the card description I've opened this PR.
Regarding the monitoring_statsd I wonder if we can split it. The way it's implemented required server_environment included, otherwise it doesn't make any sense to have it declared.
Other modules in the repo don't have direct/indirect dependency.

Can you pls take a look?

I think if these two will be validated for the server_environment removal we need to decide if we need to forward-port it to v16 and 17?

For cloud_platform, see my comment below. I believe we can drop the dependency altogether.

For monitoring_prometheus, I don't really understand the split. The extracted things don't really seem to depend on server environment. I think the server_environment dependency might have not been real there, and you can remove too
