How to display remain percent of error budget in Grafana?

[andrew-demb]

According to the documentation about available metrics [1], the following metrics are available:

1. error_budget_burn_rate: used for alerting.
2. alerting_burn_rate_threshold: used for defining the alerting threshold.
3. sli_measurement: used for visualizing the SLI over time.
4. slo_target: used for drawing target over SLI measurement.
5. events_count: used to split good / bad events in dashboards. Has two additional labels: good_events_count and bad_events_count.

I want to display in Grafana (my dashboard [2]) the amount of remaining error budget available for different error budget policies.

Something like that is available in the Google Cloud for SLOs
