Athens: Proposal: get rid of the storage.Connector

[arschles]

I'm not sure about this one. Do we need a separate Connect() function, or is it ok to connect automatically when we create a new Saver, Lister, etc...?

[robjloranger]

I like just connecting on creation, this gives the caller a ready to use Saver etc

[michalpristas]

if we have connect, we should have disconnect as well. it's not right to give a fork and keep the knife.
but i think we should go with auto-connect up to the point we need more control over this.

[kteb]

I'll work on this one.
