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

It's an alias for cobra.FixedCompletions but takes a variadic list
of strings, so that it's not needed to construct an array for this.

Update this function to accept a smaller interface, as it doesn't need
all of "CLI". Also return errors encountered during its operation (although
the caller currently has no error return on its own).
