Daily engine changes

1) Although gRPC does server side validation currently, validate basic things
on gctcli before relaying the request to the gRPC server
2) Make pair format consistent for the exchange sycner
3) Fix OKEX ticker failure due to thinking futures info is authenticated
4) Start filling out config tests
5) Extend timeout for golangci config so that AppVeyor has time to
complete (Travis is fine)
6) Add IsSupported exchange func for easy lookup
