Remove V1 APIs from Zaqar

Currently, Zaqar has tree versions of APIs,
V1, V1_1 and V2. The V1 is the oldest apis that
there is no need for them right now. All new features
are implemented under V2 APIs. So it’s time to remove
V1 APIs and optimize the Zaqar's codes.

+Remove V1 API Code From Zaqar
+=============================
+
+https://blueprints.launchpad.net/zaqar/+spec/remove-v1-api-code
+
+Now there is no need for V1 APIs, its old and could be completely replaced by V2 APIs.
+So it's time to remove it from the code tree. This action is first one of steps to optimize
+Zaqar's codes and functions.
+
+Problem description
+===================
+
+Currently, Zaqar has tree versions of APIs, V1, V1_1 and V2. The V1 is the oldest apis that
+there is no need for them right now. All new features are implemented under V2 APIs. So
+its time to remove V1 APIs and optimize the Zaqar's codes.
+
+Proposed change
+===============
+
+1. Remove all V1 APIs codes and change the basic APIs to V1_1.
+
+2. Clean the unit tests and tempest tests about V1 APIs.
+
+3. Modify the API doc according the changes.
+
+API Impact
+-----------
+
+The whole V1 APIs code will be removed from Zaqar's service.
+
+Drawbacks
+---------
+
+If someone are still using V1 APIs, they must change the API version to
+V1_1 or V2(best to V2) after Yoga release.
