Non-named docker volumes

[nikolas-digitalBabylon]

Hi,

when creating the network, there are non-explicitly named volumes created (named like 825126516f79bdca6ac80912603d7f3d52ce8925212eaf4c575fe2c620ef6966). This happens for organization peers and ordering nodes too.

I think it would be sensible to follow the naming conventions of the containers to name the volumes too. This would make it easier to monitor and examine data in them.
