6ee538549a Simplify and remove the PodSelecter struct 
There is currently only a single way to select pods to ping and there is really no way to conifgure alternatives. So this commit removes the struct and simplifes the code.

771f303062 Add rendezvous hash for selecting subset of nodes 
Select a user-defined number of pods via
rendezvous hash. This is important for larger
clusters, where the metric cardinality explosion
is too much for a single prometheus to handle.
