TODO (suggested by Nikolai)
1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies
3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)
Also need to figure out how prewhere works for projections, and
row_filter_policies.

If you push data via Buffer engine then all your queries will be done
from one user, however this is not always desired behavior, since this
will not allow to limit queries with max_concurrent_queries_for_user and
similar.

Restarting a server instance to change the interserver password results
in many replicas being out of sync until all clusters are using the new
credential.
This commit adds dynamic credential loading for both the client
(Replicated* tables) and server (InterserverIOHTTPHandler).
This commit also adds the ability to rotate credentials, i.e. accept more
than one credential during a credential change.
