add method volume_rollback_is_possible and redactor
Improve error handling
If snapshot is not reversible catch it before vm will lock and shutdown.
This is the case if zfs has an younger snapshot.

Turned out it makes no sense to duplicated DirPlugin features. So I
also changed the name to make it less confusing. So we can only
create zvols inside a zfs pool with this plugin.

This is an iplementation for file base storage types.
changes compared to patches from Alexandre:
* use correct locking
* private find_free_diskname() with bug fixes
* changed names of new methods
* always refer to base volumes in volume names
Example volume names:
local:6000/base-6000-disk-9.raw
local:6000/base-6000-disk-9.raw/7000/vm-7000-disk-9.qcow2
local:6000/base-6000-disk-9.raw/7000/base-7000-disk-10.qcow2
Currently, if a storage have an infinite timeout (nfs hard option or iscsi with high timeout for failover),
and if the storage is down or is doing ha failover with dual controller
- pvestatd hang on storage_info. (So pve-manager see the host as down, and hang on differents parts, gui,rrds display)
- pvedaemon hang on differents place (storage disk list,vm_status, hardware info,...)
- I also see a lot of qemu-img info process hanging in uninterruptible sleep state with iscsi storage.
This patch add a check to see if the storage is accessible.
For nfs and iscsi : ping with a timeout of 2 second. (Maybe this can be polish with some kind of filesystem/storage read test with timeout...)
Default for other storage plugins is to check nothing. (not a problem with sheepdog,ceph,libiscsi... as commands have timeout)

key for user admin must be specified in:
---------------------------------------
/etc/pve/priv/ceph/storeid.username.key
/etc/pve/priv/ceph/rbdtest.admin.key for this exemple.
(so we can have multiple users key by storage and multiple storage with same username)
I change "sub path" in Storage.pm to pass $storeid as third argument.
I rename property id to username, to be more clear.
removal of rbd_ prefix.
removal of trailing whitespace
