Problem:
If we use distributed queries to write, as example
the answer will be contains metadata in table format which can't be parsed in
ClickHouseDB\Statement::init()
and as a result throws "Can`t find meta" exception.This pr fixed it by adding JSON format for queries started from CREATE, DROP or ALTER.
This does not affect on non-distributed queries as the response to these queries contains nothing for those type of queries.
