[RFC PATCH 07/14] btrfs-progs: migrate rescue chunk-recover to global verbose

[Anand Jain <anand.jain@oracle.com>]

Now with this patch the btrfs rescue chunk-recover can display verbose
output either at the sub-command level or at the top level. For example
'btrfs --verbose rescue chunk-recover <>' or 'btrfs rescue chunk-recover
-v <>'.
