add podman volume reload to sync volume plugins
Libpod requires that all volumes are stored in the libpod db. Because volume plugins can be created outside of podman, it will not show all available plugins. This podman volume reload command allows users to sync the libpod db with their external volume plugins. All new volumes from the plugin are also created in the libpod db and when a volume from the db no longer exists it will be removed if possible. There are some problems: - naming conflicts, in this case we only use the first volume we found. This is not deterministic. - race conditions, we have no control over the volume plugins. It is possible that the volumes changed while we run this command. Fixes #14207 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
