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.

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.

* Convert Prometheus query response to dataframes
* Add parseResponse tests
* Fixed lint imports
* Force use UTC as timezone in timeVector
* Updated test to check timezone
Alerting for prometheus have been depending on the step parameter from each query.
In https://github.com/grafana/grafana/pull/9226 we changed the behavior for step in the
frontend which caused problems for alerting. This commit fixes that by introducing a default
min interval value so alerting always have something to depend on.
closes#9777
