REPLICA_ALREADY_EXISTS due to hardcoded UUID in the replicas

[himadrisingh]

While using

ENGINE = ReplicatedAggregatingMergeTree('/clickhouse/tables/{uuid}/{shard}', '{replica}')

New replica gets hardcoded uuid once its recreated as in this commit ac45f5e

Shouldn't this be configurable to avoid such situation.

ATTACH TABLE _ UUID '<uuid>'
(
...
)
ENGINE = ReplicatedAggregatingMergeTree('/clickhouse/tables/{uuid}/{shard}', '{replica}')
