in ExpressionAnalyzer.

In case of underlying table has an ALIAS for this column, while in Merge
table it is not marked as an alias, there will NOT_FOUND_COLUMN_IN_BLOCK
error.
Further more, when underlying tables has different default type for the
column, i.e. one has ALIAS and another has real column, then you will
also get NOT_FOUND_COLUMN_IN_BLOCK, because Merge engine should take
care of this.
Also this patch reworks how PREWHERE is handled for Merge table, and now
if you use PREWHERE on the column that has the same type and default
type (ALIAS, ...) then it will be possible, and only if the type
differs, it will be prohibited and throw ILLEGAL_PREWHERE error.
And last, but not least, also respect this restrictions for
optimize_move_to_prewhere.
v2: introduce IStorage::supportedPrewhereColumns()
v3: Remove excessive condition for PREWHERE in StorageMerge::read()

Introduce new `--connection` option, by default as a connection name
`--host` will be used.
And using --connection you also can specify --host and it will be
overwritten.
