sgr status [OPTIONS] [REPOSITORY]
Show the status of the Splitgraph engine.
If a repository is passed, show in-depth information about a repository.
If not, show information about all repositories local to the engine. This will show a list of all repositories, number of local images and tags, total repository size (theoretical maximum size and current on-disk footprint of cached objects) and the current checked out image (with LQ if the image is checked out using read-only layered querying).
