[PATCH] completion: add stash import, export

["D. Ben Knoble" <ben.knoble+github@gmail.com>]

These newer commands lack completion; implement basic support for
options and arguments.

Notes (benknoble/commits):
    - t/t9902-completion.sh passes
    - advice on completing the --to-ref argument welcome, but I also think
      it's acceptable to not offer any completion there
    
    I happened to build this off of next, but it applies cleanly to master
    (which is probably the most appropriate base).
