cbc0f56af1 Mark all input columns in LIMIT BY as required output 
The query analyzer only marks the actual arguments of LIMIT BY as required
output for the LimitBy step in the pipeline. This is fine, unless the query is
distributed, in which case the first stage might remove a column that is used
at the second stage (e.g. for ORDER BY) but is not part of the final select.

Prevent removal of any columns in LimitBy by marking all input columns as
required output.

65b654a1b6 Versatile StorageJoin 
This commit does the following:

1. StorageJoin with simple keys now supports reading
2. StorageJoin can be created with Join settings applied. Syntax is
similar to MergeTree and Kafka
3. Left Any StorageJoin with one simple key can be used as a
dictionary-like structure by function joinGet.

Examples are listed in the related test file.
