Create Snowplow monitoring framework
## Goal
Provide visibility into Snowplow events collection infrastructure. Create alerting system that would raise an alarm in case of incidents
## Breakdown
1. [ ] As the MVC I would propose to build Grafana dashboard that would include Prometheus metrics listed at https://gitlab.com/gitlab-org/growth/product-intelligence/proposals/-/blob/master/doc/snowplow/snowplow.md.
1. [ ] In parallel or as a follow up we can research and build connection between CloudWatch and Promethues, which would enable us to pull metrics from AWS, once this is done we can look into defining set of metrics to pull from AWS.
1. [ ] And finaly third workflow should focus on pulling data from SiSense into Prometheus and plotting very end of pipeline.
## Tasks
- [ ] create Grafana dashboard that plots most important metrics:
- [ ] total events
- [ ] bad events
- [ ] good events
- [ ] enriched total events
- [ ] enriched good events
- [ ] enriched bad events
- [ ] add alerting
