Takes a specific code path for data that identifies itself as dataplane instead of "guessing" what the data is.
The data must identify itself by being in the dataplane by having both the following frame metadata properties:
- TypeVersion property that is greater than 0.0
- 'Type' property
The flag is disableSSEDataplane and disables this functionality and uses the old code for all queries regardless.
See https://github.com/grafana/grafana-plugin-sdk-go/blob/main/data/contract_docs/contract.md for dataplane details.

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.

Removes various custom headers logic sprinkled around in the backend.
It should automatically be applied to outgoing HTTP requests via the
CustomHeadersMiddleware.
This also removes decryption of SecureJSONData to populate custom
headers in ngalert which seemed to have caused a ton of CPU usage.
