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!

I'm curious, are folks using goose as a Go library or a standalone CLI tool?

I was thinking of setting up github.com/pressly/goose-dialects with community-supported dialects, which can include the various flavors of ClickHouse requests. Still need to think through whether this is a good idea or not, and whether it'll even work. But it's one option, and would at least satisfy the "goose as a provider in Go code".
