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
