The api calls:
GET /storage
GET /nodes/<NAME>/storage

Have already almost all this information, missing only the whole "format" and
parts of the "content" list (the default part). This information could be simply
added there. As one of those calls must be made one way or another when using a disk/mp/efi/...
edit to get the available storages we could use it to get the needed Info, so no additional
API calls would be needed, AFAIS.

The fact that you then only get currently configured storage should not be
a problem, as disk selector can operate on existing ones anyway.

This would spare us adding additional data in the /version API call.

thoughts?
