kata-types: Support create_container_timeout set within configuration

Since it aligns with the create_container_timeout definition in
runtime-go, we need to set the value in configuration.toml in seconds,
not milliseconds. We must also convert it to milliseconds when the
configuration is loaded for request_timeout_ms.
