Previous to this we did not called the plugins update_volume_notes at
all in the case where a user delted the textarea, which results to
passing a falsy value ('').
Also adapt the currently sole implementation to delete the notes field
in the undef or '' value case. This can be done safely, as we default
to returning an empty string if no notes file exists.

we need to bump APIVER for this and can bump APIAGE, since
we only use it at this new call that can work with the default

Takes an operation, an optional requested bandwidth
limit override, and a list of storages involved in the
operation and lowers the requested bandwidth against global
and storage-specific limits unless the user has permissions
to change those.
This means:
* Global limits apply to all users without Sys.Modify on /
(as they can change datacenter.cfg options via the API).
* Storage specific limits apply to users without
Datastore.Allocate access on /storage/X for any involved
storage X.

This turns is_mountpoint more into export(5)'s `mountpoint`
property.
Given the directory storage with the properties:
path /a/b/c
is_mountpoint $value
$value = yes
Same as before, /a/b/c must be mounted.
$value = no (or not set)
Same as before, no effect.
$value = /a/b
New: /a/b must be mounted (as opposed to /a/b/c)
While the mkdir option deals with the case where we don't
want to clobber a mount point with directories (like ZFS,
gluster or NFS), putting a directory storage directly onto a
mount point is still risky:
If the path exists - which it usually does even if not
mounted - the storage will be considered successfully
activated, but empty (or with unexpected content). Some
operations will then lead to unexpected problems: the
free_disk operation for instance only warns if the disk does
not exist, but does not throw an error. In this case the
configuration might be updated without the real disk being
deleted. Once it's mounted back in, later operations which
check existing disks which are not part of the current VM
configuration (like migration) might error unexpectedly.
This adds an 'is_mountpoint' option to directory storages
which assumes the directory is an externally managed mount
point (eg. fstab or zfs) and changes activate_storage() to
throw an error if the path is not mounted.
Ideally we don't need this, but this with the directory
storage this is a user-input field which gets returned
by the storage's path() method which is used in various
external command calls.
By default a directory storage creates its path. In some
cases this can be undesired, mostly when storages have
nested paths (eg. a dir storage on a ZFS path or in an NFS
share, or inside custom mount points).
As a simple fix to this the 'mkdir' option (default ON)
can now be used to disable this behavior.
