Add custom alerts and dashboards (#1170)

- Add custom PrometheusRule alerts for gRPC, Importer and REST
- Add gRPC API dashboard
- Add REST API dashboard
- Add balances and events to the Importer dashboard
- Add namespace filter to Mirror Node dashboards
- Add `hedera.mirror.parse.duration` metric for balances
- Add `hedera.mirror.parse.latency` metric for balances
- Add record/balance file age single stat and graph to importer dashboard
- Change dashboards to use the new dynamic `$__rate_interval` variable instead of our manually specified interval approach
- Change tests to use Redis 5.0.9 to match our VM environments
- Disable kubelet monitoring in GKE since it isn't possible and generates false alerts
- Fix docker-compose not working due to lack of Redis
- Remove non-working Swagger dashboard
- Remove Go as code scanning language as it fails without Go code in master
