Issue #3046 is triggered by html/template changes in go1.9.
See https://tip.golang.org/pkg/html/template. Quote:
// To ease migration to Go 1.9 and beyond, "html" and "urlquery" will
// continue to be allowed as the last command in a pipeline. However, if the
// pipeline occurs in an unquoted attribute value context, "html" is
// disallowed. Avoid using "html" and "urlquery" entirely in new templates.
The commit also includes a trivial whitespace fix.
Adding tests for util/httputil/client with a 100% coverage.
Removing the NewDeadlineRoundTripper from util/httputil/client because
is not used.
Adding a new test util to check http.Request in http.RoundTrip interface
implementors.
With the squaring of the timestamp, we run into the
limitations of the 53bit mantissa for a 64bit float.
By subtracting away a timestamp of one of the samples (which is how the
intercept is used) we avoid this issue in practice as it's unlikely
that it is used over a very long time range.
Fixes#2674
We would overscan when hitting a value directly, interspersed with
samples in between timestamps. Apparently, that happens rarely enough
that it was only noticed recently.
Kubernetes 1.7+ no longer exposes cAdvisor metrics on the Kubelet
metrics endpoint. Update the example configuration to scrape cAdvisor
in addition to Kubelet. The provided configuration works for 1.7.3+
and commented notes are given for 1.7.2 and earlier versions.
Also remove the comment about node (Kubelet) CA not matching the master
CA. Since the example no longer connects directly to the nodes, it
doesn't matter what CA they're using.

This can happen in the situation where the system scales up the number of shards massively (to deal with some backlog), then scales it down again as the number of samples sent during the time period is less than the number received.
