* Add Loki historian store stub
* Add composite store
* Use composite store if Loki historian enabled
* Split store interface into read/write
* Make composite + historian stores read only
* Use variadic constructor for composite
* Modify Loki store enable logic
* Use dskit.concurrency.ForEachJob for parallelism
Currently, in the schema, it's a global definition called `ItemDTO`. It's hard to figure out what that is
Renaming it to `Annotation` should be more helpful
* Reduce piecemeal state fields
* Read data directly off state instead of rule
* Unify state and context into single struct
* Expose contextual information to layer above setNextState
* Work in terms of ContextualState and call historian in batches
* Call annotations service in batches
* Export format state and reason and remove workaround in unrelated test package
* Add new method to annotation service for batch inserting
* Fix loop variable aliasing bug caught by linter, didn't change behavior
* Incl timerange on annotation tests
* Insert one at a time if tags are present
* Point to rule from ContextualState rather than copy fields
* Build annotations and copy data prior to starting goroutine
* Rename to StateTransition
* Use new bulk-insert utility
* Remove rule from StateTransition and pass in directly to historian
* Simplify annotations logic since we have only one rule
* Fix logs and context, nilcheck, simplify method name
* Regenerate mock
