cmd/docker: fix completion for --context
registerCompletionFuncForGlobalFlags was called from newDockerCommand,
at which time no context-store is initialized yet, so it would return
a nil value, probably resulting in `store.Names` to panic, but these
errors are not shown when running the completion. As a result, the flag
completion would fall back to completing from filenames.

This patch changes the function to dynamically get the context-store;
this fixes the problem mentioned above, because at the time the completion
function is _invoked_, the CLI is fully initialized, and does have a
context-store available.

A (non-exported) interface is defined to allow the function to accept
alternative implementations (not requiring a full command.DockerCLI).

Before this patch:

    docker context create one
    docker context create two

    docker --context <TAB>
    .DS_Store                   .idea/                      Makefile
    .dockerignore               .mailmap                    build/
    ...

With this patch:

    docker context create one
    docker context create two

    docker --context <TAB>
    default  one      two
