lxc/image: Add GetImagesAllProjects and `GetImagesAllProjectsWithFi…

…lter` 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.
