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.
This fixes golint failures on the following files:
- test/e2e/framework/authorizer_util.go
- test/e2e/framework/cleanup.go
- test/e2e/framework/create.go
There was no reason to have two types and this avoids ~10% of allocations
on the GET code path.
```
BenchmarkGet-12 100000 109045 ns/op 17608 B/op 146 allocs/op
BenchmarkGet-12 100000 108850 ns/op 15942 B/op 132 allocs/op
```
ReplaceAllStrings always allocates, while scanning a relatively short
regex twice is slightly more CPU immediately but less later.
```
BenchmarkGet-12 100000 108824 ns/op 17818 B/op 152 allocs/op
BenchmarkGet-12 100000 108013 ns/op 17732 B/op 149 allocs/op
```
IsListType was causing ~100 allocations for a non list object. It is
used in a wide range of code, so perform a more targeted check.
The use of `%#v` in a hot return path for `fmt.Errorf()` was the main
victim.
Replace `%#v` with a typed error and create a cache of types that are
lists with a bounded size (probably not necessary, but safer).
```
BenchmarkGet-12 100000 119635 ns/op 20110 B/op 206 allocs/op
BenchmarkWatchHTTP-12 100000 65761 ns/op 7296 B/op 139 allocs/op

The kubelet was not asking for application/vnd.kubernetes.protobuf
on list and get calls. It looks like we lost that code when we
moved to cert rotation. Clean up the client initialization path
and make sure that all non-dynamic clients use protobuf by default.
This fixes golint failures under test/e2e/framework/providers/gce/.
Cleanup:
* FirewallTimeoutDefault is not used at all, so remove it.
* FirewallTestTcpTimeout, FirewallTestHttpPort and FirewallTestUdpPort
are used at test/e2e/network/firewall.go only. So move them.
