Description :
- host 'X' with 4 slots
- PE 'foo' correctly assigned to a queue instance at host X
- project 'bar'
- rqs saying 'limit projects {bar] to slots=2'
- job submitted with 'qsub -P bar -pe foo 4 script.job'

Current behavior :
'qstat -j <jobid>' only say "cannot run on host "X" because it offers only 2 slots."

Enhanced wished behavior :
qstat saying : "cannot run on host "X" because it offers only 2 slots (active
rqs 'rqs_name')"

User is then able to diagnose why a job stays in waiting state directly with qstat.
