More monitoring SLIs tuning
Following up on !4730 (merged):
- Update the thanos-store SLI to monitor all unary GPRC requests, because why shouldn't we and it looks stable
- Drop the Grafana SLIs apdex score to 0.92 while we work on improving the Thanos datasource query latency. Unfortunately
grafana_http_request_duration_seconds_bucket
doesn't go above 5s so we can't raisesatisfiedThreshold
any higher and have to lower the apdex score instead.
