[ONOS-4797] Implement the Driver for handling Arista switch
Arista switch with its recent network OS, EOS, supports remote configuration & control. The protocol for this is Arista's proprietary but REST style.
Since ONOS has already REST southbound protocol, the control of Arista switch can be easily done by using this.
- Implemnted driver Loader for Arista switch
- Implemented DeviceDescriptionDiscovery for Arista switch
- [Deleted] Implemented the method sending post to Arista switch and return the result as a String
