Parallel environment slots not updated on resize (gridengine)

[a1an77]

When resizing a gridengine cluster, the parallel environment configuration does not get updated, likely because the PE already exists and is not updated by the -Ap option of qconf. This should be detected and the -Mp option used instead to modify it.

Can you check out code for #681 and tell me if it fixes the issue?

(Note: I will be on vacation for a week starting tonight so won't be able to react quickly to follow-ups.)

It fixes the issue, thanks.

Merged into "master".

Many thanks for reporting and checking it so quickly!
