To allow updating stats based on the node name, add a helper function that will fetch the required data from 'query-named-block-nodes' and return it in hash table for easy lookup.

Detect the node names when setting block threshold and when reconnecting or when they are cleared when a block job finishes. This operation will become a no-op once we fully support node names.

qemu for some time already sets node names automatically for the block nodes. This patch adds code that attempts a best-effort detection of the node names for the backing chain from the output of 'query-named-block-nodes'. The only drawback is that the data provided by qemu needs to be matched by the filename as seen by qemu and thus if two disks share a single backing store file the detection won't work. This will allow us to use qemu commands such as 'block-set-write-threshold' which only accepts node names. In this patch only the detection code is added, it will be used later.
