* #574 consolidate some code, man the config stuff is a mess!
* #574 just use the downstream re route and the key for caching http clients
* #574 added benchmark, i was suprised to learn using a complex type was faster than a string in benchmark .net dictionary tests, hey ho probably dont have enough data in the type...
* #580 added failing test
* #580 added failing test for dynamic reroutes
* #580 added failing test for validator
* #580 validation tests passing
* #580 acceptance tests passing
* #580 got rid of the list in sdp factory
* +semver: breaking #580 service discovery provider returned by delegate must be the same as name in config, this is a breaking change because you have to specify consul now
* #580 removed use servide discovery property from file config, we dont need it, just use the service name as indicator the user wants to use service discovery for the given reroute
* #568 worked out how to check if qos handler present and kill Ocelot if options specified but no handler, need to refactor this into fluent validation style
* #568 acceptance tests to make sure Ocelot won't start if the user specifies QoSOptions but doesnt have a QoSHandler registered
* #568 Ocelot wont start if QoSOptions specified and no QoS DelegatingHandler registered e.g. no use of Ocelot.Provider.Polly. Also adds a NoQosDelegatingHandler and logs an error if ive missed something and the user can get to making the request
* #568 sadly something wierd with IServiceProvider and FluentValidation so I'm just defaulting to warning and noqosdelegatinghandler if someone doesnt register but provides options, also added basic in memory cache in case people dont use a specific package
* #555 added some tests for this issue but struggling to replicate
* #555 removed cmd=instance from service fabric code as someone who knows service fabric says its not needed
I
* #555 renamed test
* added delegate to select last handler
* #529 implemented a way we can inject the last delegating handler
* wip - moving code
* #529 removed loads of qos code and moved it into Ocelot.Provider.Polly
* #529 can now inject http client expcetions to ocelot errors mappers and updated docs
* added delegate to select last handler
* #529 implemented a way we can inject the last delegating handler
* wip - moving code
* #529 removed loads of qos code and moved it into Ocelot.Provider.Polly
* #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
