Code Issues Proposed changes

User Messages

Browse Source 
For quite some time, OpenStack services have wanted to be able to send
messages to API end users (by user I do not mean the operator, but the
user that is interacting with the client).

This patch implements basic user messages with the following APIs.
GET /messages
GET /messages/<message_id>
DELETE /messages/<message_id>

Implements the basic /messages resource and tempest tests
The patch is aligned with related cinder patch where possible:

User Messages
=============
User messages are a way to inform users about the state of asynchronous
operations. One example would be notifying the user of why a share
provisioning request failed. These messages can be requested via the
`/messages` API. All user visible messages must be defined in the permitted
messages module in order to prevent sharing sensitive information with users.
Example message generation::
from manila import context
from manila.message import api as message_api
from manila.message import message_field
self.message_api = message_api.API()
context = context.RequestContext()
project_id = '6c430ede-9476-4128-8838-8d3929ced223'
share_id = 'f292cc0c-54a7-4b3b-8174-d2ff82d87008'
self.message_api.create(
context,
message_field.Actions.CREATE,
project_id,
resource_type=message_field.Resource.SHARE,
resource_id=SHARE_id,
detail=message_field.Detail.NO_VALID_HOST)
Will produce the following::
GET /v2/6c430ede-9476-4128-8838-8d3929ced223/messages
{
"messages": [
{
"id": "5429fffa-5c76-4d68-a671-37a8e24f37cf",
"action_id": "001",
"detail_id": "002",
"user_message": "create: No storage could be allocated for this share "
"request. Trying again with a different size "
"or share type may succeed."",
"message_level": "ERROR",
"resource_type": "SHARE",
"resource_id": "f292cc0c-54a7-4b3b-8174-d2ff82d87008",
"created_at": 2015-08-27T09:49:58-05:00,
"expires_at": 2015-09-26T09:49:58-05:00,
"request_id": "req-936666d2-4c8f-4e41-9ac9-237b43f8b848",

features:
- Added new user messages API - GET /messages, GET /messages/<message_id>
and DELETE /messages/<message_id>.
- Added sorting, filtering and pagination to the user messages listing.
- Added 'message_ttl' configuration option which can be used for
configuring message expiration time.
