[collectd] [PATCH] UUID plugin for collectd

[Richard W.M. Jones]

This is an experimental plugin, just for discussion.

What it does is, if the plugin is loaded, it changes the global 
hostname_g to be the machine's UUID, where the UUID is a (supposedly) 
unique identifier for the machine.

If SMBIOS supports it, then we get it from the system BIOS (from the 
motherboard).  However this is most often useful for virtual guests, 
where we have a concept of a UUID that refers to the guest for all time, 
even if the guest is shutdown or migrated to another physical host.  The 
plugin uses a variety of different methods to try to find the UUID.

I don't really know whether updating hostname_g directly is a good idea. 
  No other plugins do it, but on the other hand it does seem to work.

Rich.
