Brian Brazil 8cd5aff8fe Send instance="" with federation if instance not set.
This is needed for federating non-instance level metrics, so they don't
end up with the instance label of the prometheus target.

Also sort external labels, so label output order is consistent.

beorn7 39c4915401 federation: Collapse time series of the same name
This will avoid duplicate MetricFamilies, thereby shrinking the size
of the federation payload and also creating legal text format.

Also, add unit tests for federation. They were also needed for the
previous state of the code, but were missing.
