> It is very heavy to create a Connection on each meta scan. Connections create
> RpcClients, RpcClients create RPC connections and all cannot be recycled.
> Tests with a lot of metascans are very heavy with the async client.
> This issue is to make anything that uses metaScans reuse the same connection.
