Create a list of companies/organizations contributing to Kubeflow (kubeflow#63)

* Start a file to keep track of organizations participating in Kubeflow.

* With Kubeflow around the corner we want to be sure to aknowledge the
  companies/organizations who are participating in Kubeflow.

* I think starting a file in source control is the best way to manage
  this over time.

* * Add information to the README about adding yourself or company.
