If a method is not allowed, real swift proxy server app will return an
HTTPMethodNotAllowed response, whereas FakeSwift would previously
*raise* HTTPNotImplemented. S3Api deliberately sends requests with
method 'TEST' which is not allowed/implemented. To workaround the
difference in real and fake swift behaviour, FakeSwift was configured
to allow the 'TEST' method, and then in some tests an
HTTPMethodNotAllowed response was registered for 'TEST' requests!
This patch modifies FakeSwift to return an HTTPMethodNotAllowed
response to the incoming request when the request method is not
allowed.
It is no longer necessary for FakeSwift to support extending the
default list of allowed methods.
