Peter Krempa c43718ef67 Document caveats of 'VIR_DOMAIN_STATS_VM' group of statistics 
The original patches adding the functionality neglected to add any form
of documentation for the stats fields returned for this group.

The stats are directly converted from qemu's 'query-stats(-schema)' QMP
command without any further interpretation. The 'query-stats-schema' has
the following disclaimer:

 Note: runtime-collected statistics and their names fall outside QEMU's usual
       deprecation policies.  QEMU will try to keep the set of available data
       stable, together with their names, but will not guarantee stability
       at all costs; the same is true of providers that source statistics
       externally, e.g. from Linux.  For example, if the same value is being
       tracked with different names on different architectures or by different
       providers, one of them might be renamed.  A statistic might go away if
       an algorithm is changed or some code is removed; changing a default
       might cause previously useful statistics to always report 0.  Such
       changes, however, are expected to be rare.

Since libvirt is not doing any form of conversion of the stats we can't
meaningfully document any of the returned fields. At the same time we
can't even meaningfully provide any form of API stability for the field
names.

Modify the documentation for the 'VIR_DOMAIN_STATS_VM' group both in the
API docs and in the virsh man page to reflect that and disclaim any form
of stability guarantees we provide normally.
