Design new command lines for Volcano.

Is this a BUG REPORT or FEATURE REQUEST?:

/kind feature
/area CLI

Description:
By now the command line 'vcctl' is split into simple commands, like vjob, vsub, vadmin, etc. What else commands do we need to make it simpler in use?

shall the command line follow slurm or lsf?

shall the command line follow slurm or lsf?

I think so, the format of slurm/LSF command lines are familiar to k8s users, like srun and brun, so a similar cmd vrun will be easily understood and in use.
