* DataSourceSettings: Add servername field to DataSource TLS config A DNS lookup URL can be provided in the DataSource URL field in order to dynamically load balance between multiple instances of a DataSource. When using mutual TLS, Golang's TLS config implementation checks that the certificate's common name (< 1.15) or subject alternative name (>= 1.15) has the same value as the domain being accessed. If the DNS entry is dynamically generated for a specific environment, the certificate cannot be generated with a name matching the dynamic DNS URL. As such, Golang offers a servername field that can be set to overwrite what value is used when checking against the certificate's common name (or subject alternative name). Without this change, Skip TLS Verify must be set to true in order for the DataSource to work, removing some of the benefits gained by using mutual TLS. This commit adds the ability to set Grafana's internal Golang TLS config servername field from the UI or a provisioned DataSource. The servername field is optional and the existing behavior is retained if the field is not set.

The open-source platform for monitoring and observability.
Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture:
- Visualize: Fast and flexible client side graphs with a multitude of options. Panel plugins offer many different ways to visualize metrics and logs.
- Dynamic Dashboards: Create dynamic & reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
- Explore Metrics: Explore your data through ad-hoc queries and dynamic drilldown. Split view and compare different time ranges, queries and data sources side by side.
- Explore Logs: Experience the magic of switching from metrics to logs with preserved label filters. Quickly search through all your logs or streaming them live.
- Alerting: Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems like Slack, PagerDuty, VictorOps, OpsGenie.
- Mixed Data Sources: Mix different data sources in the same graph! You can specify a data source on a per-query basis. This works for even custom datasources.
