1 Separate initialize from the soroswap-aggregator-adapter-interface

[joaquinsoza]

Separate initialize from the soroswap-aggregator-adapter-interface and add it as a independent trait inside the adapter

Why?
In the future another adapter could need more initialization options and we will be held back by the adapter-interface, so i think is better for us to take out the initialize from the interface trait and define it as a separate Trait inside the adapter.

An example can be found in the DeFindex adapters
