* fix folder tests

* refactor `selectorString` and remove Selector struct
* move code from selector string to BuildLogQuery
* batch requests by folder UID
* update historian annotation store to handle multiple queries
* sort folder uids to make consistent queries
* add logs to loki http
* log batch size but not content. content is logged by the client
* add method CanReadAllRules to rule authorization service
* add alias type Namespace for Folder in ngalert's models package. It implements the Namespacer interface that is used by authz logic
* update state history's backends to authorize access to rules.
* update Loki to add folders UIDs to query.
* Update BuildLogQuery to drop filter by folders if it's too long and fall back to in-memory filtering.
* Add TracedClient
* Handle errors and status codes
* Wire up tracing to normal ASH and loki annotation mapping
* Add tracing to remote alertmanager
* one more spot
* and not or
* More consistency with other grafana traces, lower cardinality name
* Move scope type vars to testutil package
* Expose parts of state historian for use in annotation backend
* Implement Loki ASH Annotation store
This store will only implement the `Get` method of a RepositoryImpl since alert state history
writes to Loki elsewhere.
