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.

This can be helpful to print the internal fields of the version
information that will contain more details about the git tree than the
short -version output will.
Tested:
- Tested getting the raw version:
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"1+", GitVersion:"v2.2.1-33-gdc4becd9765393", GitCommit:"dc4becd9765393fa05a3eb06f6af9e00068fe0c5", GitTreeState:"dirty"}
- Tested getting the simple version:
$ _output/go/bin/kubecfg -version
Kubernetes version 0.1+, build dc4becd976
- Tested getting the help output:
$ _output/go/bin/kubecfg 2>&1 | grep -- -version
-version=false: Print version information and quit
- Made sure -version=true and -version=false works, that -version with
an invalid argument works as expected (prints usage help) and that
-version followed by space will not try to use the next word as its
argument (i.e. `-version raw` prints the version but not the raw one.)

This is some cleanup that has been needed for a while.
There's still one more step that could usefully be done, which is to
split up our api package into the part that provides the helper
functions and the part that provides the internal types. That can come
later.
The v1beta1 package is now a good example of what an api plugin should
do to version its types.
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).
Allows a consumer to get at the information stored in the field selector
for querying an underlying data store. Not generic, but offers a
simple start.
Now it is possible to push these variables through ldflags:
- gitMajor
- gitMinor
- gitVersion (from latest annotated tag, output of git describe)
- gitCommit (renamed commitFromGit, intended to have the full sha1)
- gitTreeState (either "clean" or "dirty")
These are spawned into its separate source file, since they are meant to
be updated separately when a new version is released.
Also use the notation vX.Y+ for when git information is not present.
(This is consistent with the kernel build, e.g. Linux 3.15+ means its
version is >= 3.15 and < 3.16.)
v2: Added comments to the individual fields in pkg/version/base.go
Tested:
- Built it and checked the -version output:
$ hack/build-go.sh
$ output/go/bin/kubelet -version
Kubernetes version 0.1+, build c328679ef8aa
