Activate clang-tidy warning "readability-container-contains"
...
This check suggests replacing <Container>.count() by
<Container>.contains() which is more speaking and in case of
multimaps/multisets also faster.

Require mutations for per-table TTL only when it had been changed

Before this patch only per-column TTL did not requires mutation if it
had not been changed, after per-table TTL will also check whether it had
been changed or not.

CLICKHOUSE-784: reset merge tree setting
...
Add an ability to reset custom setting to default and remove it from table's metadata.
This will allow to rollback the change without knowing the system/config's default.

Projections
...
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.
