348e76fc8e Datasource: Shared HTTP client provider for core backend data sources and any data source using the data source proxy (#33439)
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.

caa1314f44 Build: use golangci-lint as a make command (#17739)
* Build: use golangci-lint as a make command

* Since gometalinter was deprecated in favor of golangci-lint so it was
  replaced by it. Responsibilities held by the gometalinter was moved to
  golangci-lint

* There was some changes in implementation (that was also mentioned in
  the code comment) between the tools, which uncovered couple errors
  in the code. Those issues were either solved or disabled by
  the inline comments

* Introduce the golangci-lint config, to make their
  configuration more manageable

* Build: replace backend-lint.sh script with make

32a45077e7 Elasticsearch: Fix pre-v7.0 and alerting error (#16904)
This fixes a regression introduced in #16646 where using Elasticsearch 
pre-v7.0 and alerting resulted in an error when trying to deserialize the 
response of total number of hits.
Total number of hits is not in use by the backend so we're removing it 
for now to make ES 6 and 7 being able to deserialize search responses 
without errors.

Closes #15622

cff2be0d66 elasticsearch: add 7.x version support (#16646)
Adds a new version option 7.0+ (70 internally).
Version 7.0+ doesn't include document types in index mappings 
so support for handling this have been added.
Version 7.0+ returns number of hits in a different way so 
support for handling this have been added.
Version 7.0+ doesn't support sending 
max_concurrent_shard_requests in multisearch header so 
support for sending this in query string have been added.
Update elastic6 docker block and dashboards (devenv) to use 
6.7.1 images, filebeat index name is now filebeat-YYYY.MM.DD 
and dashboard include correct tags and links.
Add elastic7 docker block and provisioning (devenv).
Updates documentation regarding new version.

Closes #15622
