This CL replaces a raw_ptr of AttemptManager in Job with a raw_ptr of Group so that Job can be created without AttemptManager. When a Job
is created during the current AttemptManager is failing, Group owns
a raw_ptr to the Job so that it can associate the raw_ptr to the
new AttemptManager after it recovers from the failing state.
Note that this CL doesn't implement recovering logic yet. No visible
changes. Subsequent CLs will implement recovering logic.
