fix: MPIJob worker still running when NotEnoughResources

[hackerboy01]

What this PR does / why we need it:
Before migrate v1 MPI operator to training-operator，only when all the workers of MPIJob are ready and the launcher of MPIJob is running，the state of MPIJob can change from Created to Running. So It is more reasonable to keep the STATE of MPIJob as created when NotEnoughResources.

Which issue(s) this PR fixes (optional, in Fixes #<issue number>, #<issue number>, ... format, will close the issue(s) when PR gets merged):
Fixes #1617

LGTM
@gaocegege @Jeffwan Could you double-check the Job Condition logic here? It's kind of mind-twisting.

[gaocegege]

I am not sure if it breaks other cases. For example, there is a launcher that succeeded, but one of the workers is running.

What state will be updated after the PR?

The state of Mpijob is very special and depends only on the state of the launcher. If there is a launcher that Succeeded, the state of Mpijob must be Succeeded. Only when all the workers of MPIJob are ready(running)，the launcher of MPIJob can change from Created to Running.
