Create a client for 0-stor daemon

[zaibon]

In order to finish https://github.com/threefoldtech/home/issues/343 We need to integrate the 0-stor daemon python client into JSx.

The python client is available at: https://github.com/threefoldtech/0-stor/tree/master/daemon/client/py-client

• Created a clone of the python client files in zstor in jsx zstor client directory
• Added a wrapper using jsx configuration to use the zstor client https://github.com/threefoldtech/jumpscaleX/commit/978990afe3c20cda471d0f10f942fcbc1c1b79e7

Accessible through j.clients.zstor and takes the following params:

• name : name of the client instance to be created
• ip : IP address of the daemon running
• port : adddress port of the daemon running
