Peter Krempa 154df5840d conf: Introduce <metadata_cache> subelement of <disk><driver> 
In certain specific cases it might be beneficial to be able to control
the metadata caching of storage image format drivers of a hypervisor.

Introduce XML machinery to set the maximum size of the metadata cache
which will be used by qemu's qcow2 driver.

System information specification:

Only a limited subset of entries can be modified there, so we

The DMTF spec doesn't specify any string subset, just 0 terminated
byte strings, but better be safe and restrict at least the names
to avoid problems with space normalization in attribute values,
the value is kept as the element body for maximum flexibility.
