When setting up a port forwarding with the client-go library (using the
`k8s.io/client-go/tools/portforward.PortForwarder`) with a non-defined local
port (i.e. passing `:80` as `ports` parameter to `portforward.New(...)`), a
local port will be assigned dynamically.
Currently, the local port will be _always_ 0 if it was not specified initially.
This is because the assigned local port is only set on a _copy_ of the actual
`ForwardedPort` type that is obtained in a `range` loop. This PR changes this
behaviour to set the local port at the correct instance by passing a pointer
instead of a copy to the relevant functions.

The rules for address parsing are:
* Explicitly specified addresses must bind successfully
* `localhost` is pinned to `127.0.0.1` and `::1` and at least one of those must bind successfully
This change also makes output of the command consistent
between runs with the same arguments.
Previously the command was using the range via map of addresses
which sometimes was producing different output because the order
of values is not guaranteed in Go.

It's very easy to add glog.Info(config) calls for debugging (or actual
logging). In some scenarios those configs will carry sensitive tokens
and those tokens will end up in logs or response bodies.
Leaking of those stringified configs compromises the cluster.
Also implement fmt.GoStringer.

The ContextCanceller transport wrapper blocks all API requests
after the provided context is closed. Used with the leader election
step down, a controller can ensure that new requests are not made
after the client has stepped down.

The current code simply exits without continuing to renew the lease, which means
participants using a slower lease duration might have to wait multiple minutes
before a new leader is elected. Allow an optional flag to be set on
LeaderElectionConfig that will release the lease when the calling context is
cancelled. Callers *must* ensure their lease guarded code has completed before
the context is cancelled, or other processes may acquire the lease before this
lease has released.
Add an example command that demonstrates how cancellation could be done.
As a convenience to users, make event recorder optional - not all users of the
lock code will need a recorder.

- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
