* Some fixes to the spoof.go and exporter.go
While reviewing some other CL, I saw some avenues for improving
spoof.go, to log the URL that's being fetched, which would help in test
debugging and to use switch construct, rather than nested if's.
While testing the change, I noticed some shifty loggin from the
exporter, so I fixed that as well while I was there.
* Continuation of the previous cleanups.
* Use different reporting periods based on the metrics backend. Original implementation was setting this value to 1 min to accommodate the minimum allowed value for stackdriver, but that is a sub optimal behavior for Prometheus. The change also allows operator to override the default values.
* Fix the units of reconciler latency from nano seconds to milliseconds.
