This reverts commit 07f34e2c450ad9f808b728173018b1e4d8fed458.
The [docs for ofInputStream](https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/HttpResponse.BodySubscribers.html#ofInputStream()) say:
> To ensure that all resources associated with the corresponding exchange are properly released the caller must ensure to either read all lines until the stream is exhausted, or call BaseStream.close() if it is unable or unwilling to do so. Calling close before exhausting the stream may cause the underlying HTTP connection to be closed and prevent it from being reused for subsequent operations.
When ObjectMapper.readValue is called with an InputStream it implicitly closes it, but when the library is not expecting a return type it's not passing the InputStream to Jackson, so the stream needs to be manually drained and closed as per the docs
Failure to do this leads to a leak of HttpClient socket handles, and ultimately the exception `java.net.BindException: Cannot assign requested address` when trying to make API calls
* Add Operation Servers to {operation}Call method
* add getter/setter methods
Add methods for hostIndex and customBaseUrl
* Fix return types for getters
* Add custom baseUrl logic
if you dont specifically declare a custom base url using the set method then it uses the 1st server in the operation host index array
if no custom url is set and the operation base path array is empty however, the call throws an exception
* Update server selection logic
First checks to see if a custom url is provided
If not, checks to see if operation level server is defined and uses the supplied host index (default 0)
If neither is supplied, uses the ApiClient default base path
* Update samples and docs
* [Java] deserialize to LinkedHashSet when unique items
* [Java] fix deserialization of readonly properties
* [Java] deserialize to LinkedHashSet when unique items
* Make Java libraries compatible with Gradle 7
* Make kotlin-spring compatible with Gradle 7
* Update samples to comply to Gradle 7.2
* Generate samples
* Add .circleci/config.yml
* Add Http status to the feign response wrapper
* Add Http status to the feign response wrapper
* Add Http status to the feign response wrapper
Fix typo
* Add Http status to the feign response wrapper
Fix typo
* Rename HttpResponse to ApiResponse
* Add .circleci/config.yml
* Add the property exposeResponseHeaders to feign client
This new property indicates if the feign client should expose the response headers on the API class.
* Generate new docs for exposeResponseHeaders additional property
* Rename HeaderAwareResponse to HttpResponse
* Update samples
* Refactor the implementation to use the same approach as the c# generator.
Creates a new feign operation with the suffix WithHttpInfo, this operation returns the response encapsulated in a HttpResponse class.
The HttpResponse class contains the decoded body and the response headers
* Refactor the implementation to use the same approach as the c# generator.
Generate samples
* Refactor the implementation to use the same approach as the c# generator.
Generate docs
* Use Void instead of void for HttpResponse parameterized type
