raw fields in index-patterns; more kubernetes fields

Add support for the raw fields in the index-patterns, so that they
can be used in saved searches and dashboards. For example,
add an index pattern field for `@timestamp.raw`.
Add the following kubernetes fields:
- container_name
- container_name.raw
- labels
-- deploymentconfig and deploymentconfig.raw
-- deployment
-- component
-- provider
