This review implements blueprint python-request and replaces the old
http client implementation in favor of a new one based on
python-requests.
Major changes:
* raw_request and json_request removed since everything is now being
handled by the same method "_request"
* New methods that match HTTP's methods were added:
- get
- put
- post
- head
- patch
- delete
* Content-Type is now being "inferred" based on the data being sent:
- if it is file-like object it chunks the request
- if it is a python type not instance of basestring then it'll try
to serialize it to json
- Every other case will keep the incoming content-type and will send
the data as is.
* Glanceclient's HTTPSConnection implementation will be used if
no-compression flag is set to True.
