This change updates the generic webhook logic to use a rest.Config
as its input instead of a kubeconfig file. This exposes all of the
rest.Config knobs to the caller instead of the more limited set
available through the kubeconfig format. This is useful when this
code is being used as a library outside of core Kubernetes. For
example, a downstream consumer may want to override the webhook's
internals such as its TLS configuration.

it turns out that setting a timeout on HTTP client affect watch requests made by the delegated authentication component.
with a 10 second timeout watch requests are being re-established exactly after 10 seconds even though the default request timeout for them is ~5 minutes.
this is because if multiple timeouts were set, the stdlib picks the smaller timeout to be applied, leaving other useless.

instead of setting a timeout on the HTTP client we should use context for cancellation.

Currently webhook retry backoff parameters are hard coded, we want
to have the ability to configure the backoff parameters for webhook
retry logic.
