Subject: [PATCH] Add rax_identity module

For some tasks, I need to drop the username/api_key into configuration
files. Rather than rely on how I'm calling the rax modules. It seemed
more appropriate to authenticate against Rackspace and return the wealth
of information contained in the pyrax identity payload with other
modules/templates.

+short_description: Load Rackspace Cloud Identity
+description:
+     - Verifies Rackspace Cloud credentials and returns identity information
+version_added: "1.5"
+options:
+  api_key:
+    description:
+      - Rackspace API key (overrides C(credentials))
+  credentials:
+    description:
+      - File to find the Rackspace credentials in (ignored if C(api_key) and
+        C(username) are provided)

+  username:
+    description:
+      - Rackspace username (overrides C(credentials))
+requirements: [ "pyrax" ]
+author: Christopher H. Laco, Matt Martz
+notes:
+  - The following environment variables can be used, C(RAX_USERNAME),
+    C(RAX_API_KEY), C(RAX_CREDS_FILE), C(RAX_CREDENTIALS), C(RAX_REGION).
+  - C(RAX_CREDENTIALS) and C(RAX_CREDS_FILE) points to a credentials file
+    appropriate for pyrax. See U(https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating)
+  - C(RAX_USERNAME) and C(RAX_API_KEY) obviate the use of a credentials file
+  - C(RAX_REGION) defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
