Switch 'kubectl edit' to use unstructured objects, handle schemaless objects

mark --output-version as deprecated, add example for fully-qualifying version to edit

Add 'kubectl edit' testcase for editing schemaed and schemaless data together

Add 'kubectl edit' testcase for editing unknown version of known group/kind
