Some subcommands aren't autocompleted

[mattiasb]

Issue Description

I was looking for a login sub-command as I had just learned that buildah can
push and pull images in addition to just building. I typed buildah log<TAB><TAB and got nothing. That felt weird to me so I looked at buildah --help and sure enough there was a login and logout command.

Steps to reproduce the issue

$ buildah log<TAB><TAB>

Describe the results you received

No results.

Describe the results you expected

$ buildah log
login logout
$ buildah log

buildah version output

buildah version 1.41.5 (image-spec 1.1.1, runtime-spec 1.2.1)

$ cat /usr/share/containers/storage.conf | grep -E -v '^(#.*)?$'

Additional information

For completeness I made a diff of the sub-commands that are bash-completed and
the sub-commands listed in --help:

I understand that one might want to have some difference between what's listed
in help and what's auto-completed (think the plumbing commands in git for
example) but given that login and logout is missing from bash-completion I
guess there's some unintentional differences as well. :)

Anyhow, thanks for Podman, Buildah and Skopeo! I use them almost daily!
