Currently the apiserver will not start unless a machine list or a
valid cloud provider is specified. This prevents a workflow that
manages machines solely through the minions API.
Fix the issue by changing the apiserver to only log a message that
the apiserver is being started with an empty machine list.
This patch results in a change in behavior. The apiserver will no
longer exit non-zero if a cloud provider or machine list is not
configured.
In particular, add support for -server_version=raw and use matching
format for the output of -version and -server_version.
The "normal" format is essentially defined by (version.Info) String()
method, so future updates to that method will be reflected on both.
Full version information is still available by using the "raw" flag.
Tested:
- Used cluster/kubecfg.sh to query local build and the server.
$ cluster/kubecfg.sh -version
Kubernetes version 0.2+, build 9316edfc0d2b28923fbb6eafa38458350859f926
$ cluster/kubecfg.sh -server_version
Server: Kubernetes version 0.2, build a0abb38157
$ cluster/kubecfg.sh -version=raw

Cloud providers may need specific configurations to run properly (e.g.
authentication parameters, uri, etc.).
This patch adds the simplest implementation for passing configurations
to cloudproviders: a new apiserver -cloud_config flag to specify the
path to an arbitrary configuration file.

Use images and some better formatting. Also add scripts to help prevent typos.
This based on an improved version done by Julia Ferraioli. She came up with the cool images.
This avoids some conflict with the built-in `flag` module in Go. The
module was already being renamed to `verflag` on import anyways, so we
might as well just call it that.
Tested:
- hack/build-go.sh and ran the resulting binaries with -version args.

Convert host:port and URLs passed to client.New() into the proper
values, and return an error if the value is invalid. Change CLI
to return an error if -master is invalid. Remove Client.rawRequest
which was not in use, and fix the involved tests. Add NewOrDie
Preserves the behavior of the client to not auth when a non-https
URL is passed (although in the future this should be corrected).
Also rename some to other names that make better reading. There are still a
bunch of "make" functions but they do things like assemble a string from parts
or build an array of things. It seemed that "make" there seemed fine. "New"
is for "constructors".
