1b447e8d19 Scheduler: Logging cleanup in predicates.go. 
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.

b3824cd094 Merge pull request #75570 from smarterclayton/fix_performance 
Fix a regression in watch performance and reduce allocations in the GET path
 2019-03-22 11:42:51 -07:00

0489d0b1cf Unify runtime.SerializerInfo with negotiate.AcceptedMediaTypes 
There was no reason to have two types and this avoids ~10% of allocations
on the GET code path.

```

83c41eab1d Avoid an allocation on all requests when checking for an old user agent 
ReplaceAllStrings always allocates, while scanning a relatively short
regex twice is slightly more CPU immediately but less later.

```

58fb665646 IsListType uses reflection and is expensive for hot paths 
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).

```

7d53ad1fb0 Kubelet should request protobuf from the apiserver 
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.

da7c9f70c3 Fix golint failures under test/e2e/[..]/gce 
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.
