Automatically forward core plugin request HTTP headers in outgoing HTTP requests.
Core datasource plugin authors don't have to specifically handle forwarding of HTTP
headers, e.g. do not have to "hardcode" the header-names in the datasource plugin,
if not having custom needs.
Fixes#57065
Adding support for backend plugin client middlewares. This allows headers in outgoing
backend plugin and HTTP requests to be modified using client middlewares.
The following client middlewares added:
Forward cookies: Will forward incoming HTTP request Cookies to outgoing plugins.Client
and HTTP requests if the datasource has enabled forwarding of cookies (keepCookies).
Forward OAuth token: Will set OAuth token headers on outgoing plugins.Client and HTTP
requests if the datasource has enabled Forward OAuth Identity (oauthPassThru).
Clear auth headers: Will clear any outgoing HTTP headers that was part of the incoming
HTTP request and used when authenticating to Grafana.
The current suggested way to register client middlewares is to have a separate package,
pluginsintegration, responsible for bootstrap/instantiate the backend plugin client with
middlewares and/or longer term bootstrap/instantiate plugin management.

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.

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

* Fix lint
* Fix tests
* Add case where limit <= 0 - added parametrized tests

Make sure that default timeout settings are based on configuration
parameters. This now applies for core data sources using old TSDB
contracts and new SDK contracts. Before it was only applied for old TSDB
contracts.
Also moves global setting variables to non-global (setting.Cfg).
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.
