In #50420 a few summary metrics were converted to histograms,
but the Help text in a couple of them still referred to summaries.
This fixes that help text.

Because Summary metrics can not be aggreated, convert them to histograms
so that users with HA deployments can use these metrics.
* Convert metrics registration to promauto.
* Improve help text style.

When a request going through Grafana data source proxy responds with a websocket
upgrade response we cannot override the response body since it produces an error.
This problem seems to have been introduced in Grafana v8.0 by #38962.
In addition #40303 added same problem.
Fixes#41292
Uses new httpclient package from grafana-plugin-sdk-go introduced
via grafana/grafana-plugin-sdk-go#328.
Replaces the GetHTTPClient, GetTransport, GetTLSConfig methods defined
on DataSource model.
Longer-term the goal is to migrate core HTTP backend data sources to use the
SDK contracts and using httpclient.Provider for creating HTTP clients and such.
