* #529 removed consul deps and introduced delegate to find service discovery provider
* +semver: breaking moved consul configuration to package..introduced mechanism for packages to configure Ocelot pipeline
* Made the file config poller use IHostedService, bit more generic, not just need to provide the correct implementations of the repo services and it will poll anything..this means we can open up redis for #458
