I think this receive could be encapsulated inside the carbon_sever module- ex. wait_wait_for_client or sth similar. Btw we can name it carbon_cache_server. Initially, I thought that it might have something to do with carbon copies.

Good idea. I'll do that.

What about testing title's feature - skipped hooks? I see two ways of doing that, either extend carbon_server and make it understand metric reports or use meck to validate if "mongoose_metrics:update/2" has/hasn't been called. |

Done. Also I renamed the carbon_server and applied your suggestion. |

This PR prevents creating a spiral metric for skipped hook. Such metric is dangerous because it may have lot of (tens of thousands) updates in a minute which can lead to too long message inbox for process holding this metric and can crash
exometer_reporter.Also, this PR adds some tests for metric subscriptions.
