Add support to replicated clickhouse cluster

[jderusse]

When running goose on a clickhouse cluster, it fails to get the list of "previous" migrations (sometime querying a node a get a partial list of migrations)

Possible fix:

1. change the engine

- ENGINE = MergeTree()
+ ENGINE = ReplicatedMergeTree('/clickhouse/{cluster}/tables/{shard}/{database}/{table}', '{replica}')

Not sure how this can be defined in goose via the CreateTable function (or should it be a new driver ? 🤔 )

It could be possible to have it depend on an environment variable. To be able to support both replicated and non-replicated setups I do the following in my own migrations:

ENGINE = ${CH_ENGINE:-ReplicatedMergeTree}

Something similar could be possible here!
