This is the second half for the previous series [0].
This series aims to allow offline migration with '--targetstorage'
and improve handling unsued/orphaned disks when migrating.
It also makes it possible to migrate volumes between storages with
a 'path' and storages without if the target storage uses the standard
naming scheme and the source format is supported (e.g. migrating raw
volumes between storages with a path and lvm storages).
It also adds an apiinfo call to pvesm that can be used to determine
APIVER and APIAGE of the remote node and does some general refactoring
regarding volume iterators.
The series is organised as follows:
#1-#7 introduce and implement volume related helpers
Mutual dependencies for both qemu-server and container with guest-common,
to be precise #1-#3 <-> #5 and #1-#3 <-> #7.
#8 adds the apiinfo helper
#9-#12 changes storage_migrate interface
Another round of mutual dependencies, this time for storage with each
of guest-common, qemu-server, container.
#13-#18 implement the goals for this series, and the last inter-package
dependency is here, because #15 (qemu-server) depends on #13 (storage)
#19-#22 improve logging and refactor some code with foreach_volume
Changes from v2:
* add apiinfo call and check if remote side supports allow_rename
* add valid_volume_keys and implement (and make use of) foreach_volume
iterator
* make volname_for_storage a local function and avoid
requiring a new print_volname for plugins
* parse vm_state in parse_volume instead of parse_drive
