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
