Time has a limited set of allowed characters and so can bypass part of
the expensive checking done for valid JSON characters.

Can improve CRD watch performance by 5-10% for small objects.
This fixes golint failures on the following files:
- test/e2e/framework/deployment_util.go
- test/e2e/framework/exec_util.go
Cleanup:
- ScaleDeployment() was not used at all, so let's remove it.
- ExecCommandInPod() and ExecCommandInPodWithFullOutput() were called
in the framework only, so let's make them local.
In addition, this replaces the combination of GetCPUSummary() and
FormatCPUSummary() with LogCPUSummary() in e2e/node/kubelet_perf.go
because that is completely same.
Recent change to hack/lib/golang.sh broke the build on MacOS this way:

It was caused by 'binaries' array not being declared with 'local -a'.
It looks like MacOS' old bash version makes an array to contain first
empty element if declared this way.
The fix has been tested on MacOS High Sierra and Linux openSUSE 42.3 (x86_64)

This is some light cleanup of logs in predicates.go. In particular, some
log lines have details clarified that will make debugging easier.
I have not touched any VLOG messages, since those usually have plenty of
detail.

- test/e2e/framework/authorizer_util.go
