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.
* Alerting: Remove and revert flag alertingBigTransactions
This is a partial revert of #56575 and a removal of the `alertingBigTransactions` flag.
Real-word use has seen no clear performance incentive to maintain this flag. Lowered db connection count
came at the cost of significant increase in CPU usage and query latency.
* Fix lint backend
* Removed last bits of alertingBigTransactions

* Alerting: Tiny refactor on the eval and schedule packages
two very small things:
- We had a constructor on something called a `Context` which is not a `context.Context` so let's just name that constructor `NewContext`
- The user that we use to run query evaluations is the same (with some variation) abstract it to a function so that it can be re-used when necessary.

* Alerting: Add endpoint to revert to a previous alertmanager configuration
This endpoint is meant to be used in conjunction with /api/alertmanager/grafana/config/history to
revert to a previously applied alertmanager configuration. This is done by ID instead of raw config
string in order to avoid secure field complications.

This commit adds a number of limits to the Grafana flavor of the
Prometheus Rules API:
1. `limit` limits the maximum number of Rule Groups returned
2. `limit_rules` limits the maximum number of rules per Rule Group
3. `limit_alerts` limits the maximum number of alerts per rule
It sorts Rule Groups and rules within Rule Groups such that data in the
response is stable across requests. It also returns summaries (totals) for
all Rule Groups, individual Rule Groups and rules.

* Alerting: Respect "For" Duration for NoData alerts
This change modifies `resultNoData` to be more inline with the logic of the other state handlers.
The main effects of this are:
1) NoData states with NoDataState config set to Alerting will respect "For" duration.
2) Prevents zero value in StartsAt and EndsAt for alerts that have only even been in normal state. This includes state transitions from NoDataState=OK and ExecErrState=OK.
3) Better state transition logging.
