For now, these are not exported and included in the cli/commands/contexts
package; a copy of this also lives in cmd/docker, but we need to find a
good place for these completions, as some of them bring in additional
dependencies.
Commands that accept multiple arguments provide completion, but removing
duplicates:
docker context inspect<TAB>
default desktop-linux (current) production tcd
docker context inspec default<TAB>
desktop-linux (current) production tcd
docker context inspect default tcd<TAB>
desktop-linux (current) production
For "context export", we provide completion for the first argument, after
which file-completion is provided:
# provides context names completion for the first argument
docker context export production<TAB>
default desktop-linux (current) production tcd
# then provides completion for filenames
docker context export desktop-linux<TAB>
