Compute metric with evaluate from main process only, avoiding bug in multinode evaluate.
Enforce --multi_gpu on multiple nodes. Moreover, make sure that each rank gets correctly addressed based on the $SLURM_PROCID. $SLURM_NNODES has now been deprecated and replaced by $SLURM_JOB_NUM_NODES. Fixed typo in $CMD as well.

What does this PR do?
The SLURM multinode submit script doesn't work for multiple reasons (see also #1239 which is still open). This PR aims at solving some of those issues, namely:
$CMDcommand$SLURM_NNODESwas recently deprecated in favour of$SLURM_JOB_NUM_NODES--multi-gpuand the rank of each process has to be set with--machine-rankcomplete_nlp_exampledoesn't handle distributed evaluation correctly. In particular, either the evaluate GLUE mrpc metric has to be loaded with the--num_processand--process_idflags (which will subsequently fail due to several breakages due to recentdatasetsevaluate#542 & related) or metric computation has to happen only on the main process. This PR goes for the second.Fixes #3206
