Removing unconventional two letter flags + adding dashes in-between two letter words.

[cdrage]

Using multi-two-letter flags is unconventional and against common CLI usages.

For example:

   --replicationcontroller, --rc        Generate a Kubernetes replication controller object

Should either be JUST --rc or --replicationcontroller.

Ideally, flags with two names should have dashes in between them, such as --replication-controller.

Common CLI tools such as kubectl and oc use these conventions and considering most of the users are coming from these tools, we should follow suit.

PR is available here with these changes: #304

Kubectl example using two-letter words with dashes:

      --dry-run=false: If true, only print the object that would be sent, without sending it.
      --generator='deployment-basic/v1beta1': The name of the API generator to use.
      --image=[]: Image name to run.
      --no-headers=false: When using the default or custom-column output format, don't print headers.
  -o, --output='': Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
      --output-version='': Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
      --save-config=false: If true, the configuration of current object will be saved in its annotation. This is useful when you want to perform kubectl apply on this object in the future.
      --schema-cache-dir='~/.kube/schema': If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema'
  -a, --show-all=false: When printing, show all resources (default hide terminated pods.)
      --show-labels=false: When printing, show all labels as the last column (default hide labels column)
      --sort-by='': If non-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
      --template='': Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].
      --validate=true: If true, use a schema to validate the input before sending it

And when referencing replication controller, it's conventionally used with a dash in-between the words:

Okay since #304 was merged, this can be closed.
