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.

* initial commit: add setting and stub

* typo

* added test stub

* fix

* wip merging new integration test and code proto

* adding steps interpreters

* adding firstly proposed solution (moving parts etc)

* added checking zookeeper path existence

* fixing the include

* fixing and sorting includes

* fixing outdated struct

* fix the name

* added ast ptr as level of indirection

* fix ref

* updating the changes

* working on test stub

* fix iterator -> reference

* revert rocksdb submodule update

* fixed show privileges test

* updated the test stub

* replaced rand() with thread_local_rng(), updated the tests

updated the test

fixed test config path

test fix

removed error messages

fixed the test

updated the test

fixed string literal

fixed literal

typo: =

* fixed the empty replica error message

* updated the test and the code with logs

* updated the possible test cases, updated

* added the code/test milestone comments

* updated the test (added more testcases)

* replaced native assert with CH one

* individual replicas recursive delete fix

* updated the AS db.name AST

* two small logging fixes

* manually generated AST fixes

* Updated the test, added the possible algo change

* Some thoughts about optimizing the solution:

ALTER MOVE PARTITION .. TO TABLE -> move to detached/ + ALTER ... ATTACH

* fix

* Removed the replica sync in test as it's invalid

* Some test tweaks

* tmp

* Rewrote the algo by using the executeQuery instead of

hand-crafting the ASTPtr.

Two questions still active.

* tr: logging active parts

* Extracted the parts moving algo into a separate helper function

* Fixed the test data and the queries slightly

* Replaced query to system.parts to direct invocation,

started building the test that breaks on various parts.

* Added the case for tables when at least one replica is alive

* Updated the test to test replicas restoration by detaching/attaching

* Altered the test to check restoration without replica restart

* Added the tables swap in the start if the server failed last time

* Hotfix when only /replicas/replica... path was deleted

* Restore ZK paths while creating a replicated MergeTree table

* Updated the docs, fixed the algo for individual replicas restoration case

* Initial parts table storage fix, tests sync fix

* Reverted individual replica restoration to general algo

* Slightly optimised getDataParts

* Trying another solution with parts detaching

* Rewrote algo without any steps, added ON CLUSTER support

* Attaching parts from other replica on restoration

* Getting part checksums from ZK

* Removed ON CLUSTER, finished working solution

* Multiple small changes after review

* Fixing parallel test

* Supporting rewritten form on cluster

* Test fix

* Moar logging

* Using source replica as checksum provider

* improve test, remove some code from parser

* Trying solution with move to detached + forget

* Moving all parts (not only Committed) to detached

* Edited docs for RESTORE REPLICA

* Re-merging

* minor fixes

af311c8642 Add acl for move partition between shards
We can not easily verify permissions on destination shard

and instead we require a custom grant that can be given to

superadmins.

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.
