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.
