Finch autocompletion doesnt pick up subcommands

[ollypom]

Describe the bug The Finch CLI's auto completion today does not work as expected as the majority of sub commands / flags are not known by the Finch CLI. This is because today the majority of sub commands and flags are owned by nerdctl not finch.

Steps to reproduce Top level commands are available with auto completion:

$ finch [tab][tab]
build       container   help        inspect     logs        pull        run         system      version
builder     cp          history     kill        network     push        save        tag         vm
commit      create      image       load        pause       restart     start       top         volume
completion  events      images      login       port        rm          stats       unpause     wait
compose     exec        info        logout      ps          rmi         stop        update

However sub commands and flags are not

$ finch compose [tab][tab]
.

$ finch compose - [tab][tab]
--debug  --help   -h

With the exception of VM level sub commands, which are first class citizens in the Finch CLI

$ finch vm [tab][tab]
init    remove  start   status  stop

$ finch vm remove - [tab][tab]
--debug  --force  --help

Expected behavior Auto completion to work for all sub commands and flags.

Additional context

In the interim, should we disable auto completion in Finch?
