it is now necessary for storages to support the 'rootdir' content
in order to create/start containers on them. all native storage
plugins already report the rootdir content correctly.

Sorry, forgot to include. Changes v1 -> v2:
- Added a commit message which explains the need of content type 'rootdir'
- code style
- new behavior should now be the same as old behavior (regarding native
storage plugins)
- updated error messages

For creation, this was already required in the past. For startup, while
such a change can be fine for 7.0, if we go for it, we should make the
equivalent change for VMs too (requiring the 'image' content type to be
configured for the relevant storages upon startup).

Note that it's not necessarily the storage type which does not support
'rootdir', it could simply be that the concrete storage is not
configured for 'rootdir' content type. So the error message should use
the storage ID instead of the storage type.
