No way to omit parameters for Replicated* table engines constructor

[bgo-bc]

Describe the bug
Clickhouse allows omitting the parameters for Replicated* engines (https://clickhouse.com/docs/engines/table-engines/mergetree-family/replication)

For example, in the text below you would replace:

ENGINE = ReplicatedMergeTree(
    '/clickhouse/tables/{shard}/table_name',
    '{replica}'
)

with:

ENGINE = ReplicatedMergeTree

But in clickhhouse-sqlalchemy, the table_path and replica_name are required parameters:

class ReplicatedMergeTree(ReplicatedEngineMixin, MergeTree):
    def __init__(self, table_path, replica_name,
                 *args, **kwargs):
        ReplicatedEngineMixin.__init__(self, table_path, replica_name)
        MergeTree.__init__(self, *args, **kwargs)

Expected behavior
clickhouse-sqlalchemy should also allow these parameters to be omitted
