generic NotFound exception is often raised when image is not found

[Alex Meade]

Numerous places such as glance/db/__init__.py, glance/store/swift.py, and glance/store/__init__py raise and catch a NotFound exception when an image can not be found. It would be better to have something like an ImageNotFound exception raised and caught to be sure that it was an Image that could not be found and to have image specific information in the exception.

For example, tasks use a TaskNotFound exception that allows for a task_id kwarg to be passed in.
