60 isolate connector

[0xp3gasus]

Description

Connector can be isolated from blockchain nodes. It supports multiple tokens at the same time in differents networks. With the Admin package created, it is posible to add, update and remove tokens in differents networks. The rest of the functionality of the connector is the same.

Endpoint paths have been replace from /rpc and /ws to {coin}/{network}/rpc and /{coin}/network}/ws
