[krajorama]

Is your feature request related to a problem? Please describe.

Make it possible to easily set up HA deduplication / HA tracker The feature is documented here: https://grafana.com/docs/mimir/latest/operators-guide/configuring/configuring-high-availability-deduplication/

Describe the solution you'd like

Proposed requirement: when HA tracker is enabled the chart should make it work without requiring the user to set up anything else.

Proposal 1: run etcd directly with statefulsets (like we do with memcached now) Proposal 2: use memberlist as HA tracker

Note: the solutions above are untested, but due to issues with etcd operator, do not include the current (Mimir 2.1) solution. Ref: https://raintank-corp.slack.com/archives/C029912SXT8/p1656061889640419?thread_ts=1656057518.814969&cid=C029912SXT8
