What happened + What you expected to happen

When trying to specify setup_timeout_seconds while using container runtime_env this exception is thrown:

The 'container' field currently cannot be used together with other fields of runtime_env. Specified fields: dict_keys(['container', 'config'])

Expect to be able to specify this field when using container runtime_env.
