Implement mapping of HttpResponseMessage to CachedResponse to fix #152 (#153)

* changed name to cache options to fix issue #146

* Add acceptance test that exposes JSON deserialization bug from issue #146

- Create InMemoryJsonHandle for CacheManager that mimics DictionaryHandle but uses ICacheSerializer to serialize/deserialize values instead of saving references
- Add CacheManager.Serialization.Json package
- Add StartupWithCustomCacheHandle class that extends Startup and overrides ConfigureServices to register InMemoryJsonHandle
- Add GivenOcelotIsRunningUsingConsulToStoreConfigAndJsonSerializedCache method to initiate Ocelot with StartupWithCustomCacheHandle
- Add test should_return_response_200_with_simple_url_when_using_jsonserialized_cache

* Create Acceptance test that exposes issue #152

- Add GivenOcelotIsRunningUsingJsonSerializedCache() that initializes Ocelot with InMemoryJsonHandle
- Add should_return_cached_response_when_using_jsonserialized_cache test

* Change Consul port to 9502 on should_return_response_200_with_simple_url_when_using_jsonserialized_cache() test

* Implement mapping of HttpResponseMessage to CachedResponse to enable distributed caching

- Add CachedResponse class that holds HttpResponse data
- Add mapping methods in OutputCacheMiddleware to create HttpResponseMessage from CachedResponse and vice versa
- Replace HttpResponseMessage with CachedResponse in services registrations
- Replace HttpResponseMessage with CachedResponse in OutputCacheController's IOcelotCache

* Fix unit tests for OutputCacheMiddleware and OutputCacheController by replacing HttpResponseMessage with CachedResponse

* Add .editorconfig with default identation settings (spaces with size 4)

* Re-format broken files with new identation settings

* Add Startup_WithConsul_And_CustomCacheHandle class

- Use Startup_WithConsul_And_CustomCacheHandle in GivenOcelotIsRunningUsingConsulToStoreConfigAndJsonSerializedCache step

* Do minor cleanups

- Rename StartupWithCustomCacheHandle to Startup_WithCustomCacheHandle for better readability
- Remove cachemanager settings Action in Startup since it is not used anymore

* Drop Task in CreateHttpResponseMessage - unnecessary overhead

* Make setters private in CachedResponse

- Rework CreateCachedResponse to use new CachedResponse constructor
