Move okhttp client from http-api

The client has been recreated with a new builder off of the http-api
client for awhile anyway since runelite-client has multiple other
requirements (caching, tls, etc). This fully moves creation of the
okhttp client into both http-service and runelite-client separately.

I've kept the CLIENT field in http-api for now since a few external
plugins depend on it currently.
