* Alerting: Refactor readiness check
Moves the readiness check to the mimir client and removes the need to assert that we have senders - it already has a queue and can hold notifications until we're ready to send them.

* Alerting: Add a sync interval for ApplyConfig in remote secondary mode
* remove out of scope code
* remove parentheses after CleanUp for consistency in test comments
* Add comment to ApplyConfig
* Alerting: Introduce a Mimir client as part of the Remote Alertmanager
Mimir client that understands the new APIs developed for mimir. Very much a WIP still.
* more wip
* appease the linter
* more linting
* add more code
* get state from kvstore, encode, send
* send state to the remote Alertmanager, extract fullstate logic into its own function
* pass kvstore to remote.NewAlertmanager()
* refactor
* add fake kvstore to tests
* tests
* use FileStore to get state
* always log 'completed state upload'
* refactor compareRemoteConfig
* base64-encode the state in the file store
* export silences and nflog filenames, refactor
* log 'completed state/config upload...' regardless of outcome
* add values to the state store in tests
* address code review comments
* log error from filestore

* Alerting: Add GetFullState method to FileStore
* make tests compile, create stateStore in NewAlertmanager
* return errors instead of logging, accept an arbitrary number of strings
* make NewAlertmanager() accept a stateStore
* Remote Alertmanager(refactor): Only parse the URL once
Exactly what it says in the tin.

* Alerting: Introduce a Mimir client as part of the Remote Alertmanager
This is our first attempt at making Grafana communicate use Mimir as a backend - it uses a new set of APIs that we've developed on the Mimir side to upload the grafana configuration and alertmanager state so that it can then be ported over.
Codewise, we've introduced a couple of things:
A client to isolate in its own package all the communication that happens with Mimir
A few changes to the remote/alertmanager to include uploading the configuration and state when it starts
A few refactors that align a bit better with the design approach that we're thinking
An integration tests again these newly developed APIs using a custom image

We'll avoid import cycles when using components from other packages. In addition to that, I've created an `Options` approach for the multiorg alertmanger to allow us to override how per tenant alertmanagers are created.
