James E. Blair 1958bbad03 Add nodeset alternatives
This feature instructs Zuul to attempt a second or more node request
with a different node configuration (ie, possibly different labels)
if the first one fails.

It is intended to address the case where a cloud provider is unable
to supply specialized high-performance nodes, and the user would like
the job to proceed anyway on lower-performance nodes.

Nodesets may now express an ordered list of alternatives so that
if Nodepool is unable to fulfill a request for certain labels, one
or more alternative Nodesets may be attempted instead. See
:attr:`nodeset.alternatives` for details.
