LXC: Add GetImagesAllProjects and GetImagesAllProjectsWithFilter …

…client functions and interfaces to `simplestreams_images.go`

This commit fixes a regression introduced with support for fetching
images across all projects by adding `GetImagesAllProjects` and
`GetImagesAllProjectsWithFilter` functions to
`client/simplestreams_images.go`, and moving their method signatures to
the ImageServer interface.
