Subject: ceph-volume: fix argparse dmcrypt opts: use str type
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F68769%2Fhead;p=ceph.git

ceph-volume: fix argparse dmcrypt opts: use str type

argparse's `type` has to be a callable that turns the CLI string into the
stored value.

Optional[str] is a typing construct. Newer argparse treats that specially
and fails with "invalid Optional value".

default=None already means the flag is optional.

Fixes: https://tracker.ceph.com/issues/76433
