Subject: [PATCH] Improve CLI docker caching (#612)

Currently, the CLI docker image copies the entire `controller`
directory, though the CLI only requires a few of its subdirectories.
This causes the CLI's docker cache to be needlessly invalidated when,
for instance, a service implementation changes.

By restricting the copied directories to `controller/{api,public,util}`,
build caching is improved.
