* Alerting: Pass metrics Registerer into NewExternalAlertmanagerSender.
I will work on a separate change to export the metrics from Grafana, this
is a little more complicated.
* Typo
* Alerting: fix race condition in (*ngalert/sender.ExternalAlertmanager).Run
* Chore: Fix data races when accessing members of *ngalert/state.FakeInstanceStore
* Chore: Fix data races in tests in ngalert/schedule and enable some parallel tests
* Chore: fix linters
* Chore: add TODO comment to remove loopvar once we move to Go 1.22
* Alerting: Rename remote.ExternalAlertmanager to remote.Alertmanager
* Alerting: Send alerts to the remote Alertmanager
* add ticker to readiness check, add tests
* use options when creating a new sender.ExternaAlertmanager
* unexport defaultMaxQueueCapacity
* delete unused defaultConfig field
* add debug log line when sending alerts to the remote alertmanager
* move and refactor readiness check
* update tests to not include defaultConfig
* Remove URL-based alertmanagers from endpoint config
* WIP
* Add migration and alertmanagers from admin_configuration
* Empty comment removed
* set BasicAuth true when user is present in url
* Remove Alertmanagers from GET /admin_config payload
* Remove URL-based alertmanager configuration from UI
* Fix new uid generation in external alertmanagers migration
* Fix tests for URL-based external alertmanagers
* Fix API tests
* Add more tests, move migration code to separate file, and remove possible am duplicate urls
* Fix edge cases in migration

* Audit logs in sender package
* Fix casing and touch up a few key names
* Avoid logging entire alert struct
* Log configuration ID being applied
* Revert change to errorf rather than log
* Tune levels further and remove some redundancies
* Adjust logger naming and standardize log context
* Adjust logger naming in router
* Move log and get rid of dead error handling code
* Alerting: Sanitize invalid label/annotation names for external alertmanagers
Grafana's built-in Alertmanager supports both Unicode label keys and values; however, if using an external
Prometheus Alertmanager label keys must be compatible with their data model.
This means label keys must only contain ASCII letters, numbers, as well as underscores and match the regex
`[a-zA-Z_][a-zA-Z0-9_]*`.
Any invalid characters will now be removed or replaced by the Grafana alerting engine before being sent to
the external Alertmanager according to the following rules:
- `Whitespace` will be removed.
- `ASCII characters` will be replaced with `_`.
- `All other characters` will be replaced with their lower-case hex representation.
* Prefix hex replacements with `0x`
* Refactor for clarity
* Apply suggestions from code review

* Introduce AlertsRouter in the sender package, and move all fields and methods related to notifications out of the scheduler to this router.
* Introduce a new interface AlertsSender in the schedule package and replace calls of anonymous function `notify` inside the ruleRoutine to calling methods of that interface.
* Rename interface Scheduler in api package to ExternalAlertmanagerProvider, and replace scheduler with AlertRouter as struct that implements the interface.
* Alerting: Refactor & fix unified alerting metrics structure
Fixes and refactors the metrics structure we have for the ngalert service. Now, each component has its own metric struct that includes the JUST the metrics it uses. Additionally, I have fixed the configuration metrics and added new metrics to determine if we have discovered and started all the necessary configurations of an instance.
This allows us to alert on `grafana_alerting_discovered_configurations - grafana_alerting_active_configurations != 0` to know whether an alertmanager instance did not start successfully.
* Alerting: Send alerts to external Alertmanager(s)
Within this PR we're adding support for registering or unregistering
sending to a set of external alertmanagers. A few of the things that are
going are:
- Introduce a new table to hold "admin" (either org or global)
configuration we can change at runtime.
- A new periodic check that polls for this configuration and adjusts the
"senders" accordingly.
- Introduces a new concept of "senders" that are responsible for
shipping the alerts to the external Alertmanager(s). In a nutshell,
this is the Prometheus notifier (the one in charge of sending the alert)
mapped to a multi-tenant map.
There are a few code movements here and there but those are minor, I
tried to keep things intact as much as possible so that we could have an
easier diff.
