Deprecate all of the compute image proxy APIs

This is the only proxy API we support in SDK. We should stop doing that.
For now, just deprecate it.

Some examples are updated to use the image API.

+    The following Compute service proxy methods are now deprecated:
+
+    * ``find_image``
+    * ``get_image``
+    * ``delete_image``
+    * ``images``
+
+    These are proxy APIs for the Image service. You should use the Image
+    service instead via the Image service proxy methods.
