Generic database interface with custom DBMS implementation (currently only clickhouse).
The ClickhouseClient takes a generic parameter implementing the ClickhouseDBMS trait which for all intents and prorpuses is a set of unit struct implementing the ClickhouseTable trait that can be used with this client.
When creating sets of tables, first call the clickhouse_dbms! macro, then define each of the tables with the remote_clickhouse_table! proc-macro
