This patch adds a test in the create bucket to exercise the parsing of
the cpus parameter. This patch utilizes the new form of getVcpuInfo
from [PATCH 1/3].

+# This test will examine Xend's cpu/cpus parameter parsing ability. The cpus
+# parameter controls which physical cpus the domain's vcpus run upon. We can
+# set a single cpumask for all vcpus, or we can build up lists of cpumasks
+# to be applied individually. The test covers the following cases:
+#
+# single vcpu tests
+# multi-vcpu tests using same values
+# multi-vcpu tests using differing values per-vcpu
+# multi-vcpu tests as above, mix-notation (using [ ] and ' ' interspersed)
+#
+# format: (#vcpus, cpus= value, list of resulting affinity values)
