In resource.Builder ContinueOnError() should actually do so.
Reorganized util.CheckErr() to make it display bulk errors more
effectively and be more reusable. Clarified that CheckErr is not
specific to kubectl in Godoc. Changed the "Error: " prefix to
"error: " to more closely match Unix conventions.
Omit glog prefix when v < 2, show multiline errors for configuration
problems, add new generic messages for server errors that hide some
complexity that is not relevant for users.
Will allow xarg behavior to fetch resources across multiple types.
Changes 'create', 'get', 'update', 'stop', and 'delete' to output
<resourceType>/<name>.
