* Alerting: Expect 406s from the remote Alertmanager during the readiness check
* make it clear in the warning logs that we'll attempt to send the confgiuration/state without comparing in case of error pulling the current state/config
* 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
* Alerting: Add metrics to the remote Alertmanager struct
* rephrase http_requests_failed description
* make linter happy
* remove unnecessary metrics
* extract timed client to separate package
* use histogram collector from dskit
* remove weaveworks dependency
* capture metrics for all requests to the remote Alertmanager (both clients)
* use the timed client in the MimirAuthRoundTripper
* HTTPRequestsDuration -> HTTPRequestDuration, clean up mimir client factory function
* refactor
* less git diff
* gauge for last readiness check in seconds
* initialize LastReadinesCheck to 0, tweak metric names and descriptions
* add counters for sync attempts/errors
* last config sync and last state sync timestamps (gauges)
* change latency metric name
* metric for remote Alertmanager mode
* code review comments
* move label constants to metrics package
* 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: 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: 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
