   In theory, min res for IT in theory: `driver res * n parallel + executor res 
* 1 + extra left`.
   
   - min cpu requirement: `1 * n + 1 * 1 + 1`
   - min mem requirment: `1.5 * n + 1.5 * 1 + 1`
   
   - for queue in this PR, need about 6U9G before
   - for priority in this PR, need about 5U7G before.
   - Other volcano tests can be compelted in 4U6G
   
   I just thought can we reduce the limit of volcano IT. 😂 otherwise, need more 
res for dev and ci.
