[RFC PATCH 2/2] tools/cpupools: Give a name to unnamed cpupools

[Luca Fancellu <luca.fancellu@xxxxxxx>]

With the introduction of boot time cpupools, Xen can
create at boot time many cpupools different from the
cpupool with id 0.

Since these newly created cpupools can't have an
entry in Xenstore, name them with the same convention
used for the cpupool 0: Pool-<cpupool id>.
