The LoadTLSFiles method is useful for configuration code that needs
to read the current client config and get values out for creating
other config files.

Can be set by other clients
client.Config describes how to make a client connection to a server
for HTTP traffic, but for connection upgrade scenarios cannot be
used because the underlying http.Transport object can't allow the
connection to be hijacked. Reorganize the TLS and connection wrapper
methods so that a sophisticated client can do:
cfg := &client.Config{...} // from somewhere
tlsConfig, _ := client.TLSConfigFor(cfg)
_ := conn.Dial(...)
rt := MyRoundTripper() // some func that implements grabbing requests
wrapper, _ := client.HTTPWrappersFor(cfg)
req := &http.Request{}
req.Header.Set("Connection-Upgrade", ...)
_, := wrapper.RoundTrip(req)
// rt has been invoked with a fully formed Req with auth
rt.Req.Write(conn)
// read response for upgrade
It would be good to have utility function that does more of this,
but mostly enabling the HTTP2/SPDY client exec function right now.
RESTClient is an abstraction on top of arbitrary HTTP endpoints that
follow the Kubernetes API conventions. Refactored RESTClientFor so that
assumptions that are Kube specific happen outside of that method (so
others can reuse the RESTClient). Added more validation to client.New
to ensure clients give good input. Exposed APIVersion on RESTClient
as a method so that wrapper code (code that adds typed / structured
methods over rest endpoints like client.Client) can more easily make
decisions about what APIVersion it is running under.
Replaces the client public interface but leaves old references to "minions"
for a later refactor. Selects the path "nodes" for v1beta3 and "minions"
for older versions.
* Allows consumers to provide their own transports for common cases.
* Supports KUBE_API_VERSION on test cases for controlling which
api version they test against
* Provides a common flag registration method for CLIs that need
to connect to an API server (to avoid duplicating flags)
* Ensures errors are properly returned by the server
* Add a Context field to client.Config
