Issue with partitions with different GPUs

[t20100]

There is a limitation in the current fetching of parititon information when there is different gres (e.g., GPU) in the same partition, e.g.:

dev 1/0/0/1 128 32/0/96/128 gpu:MYGPU:2(S:0-1) 520000 infinite
dev 0/0/1/1 128 0/0/128/128 gpu:MYGPU:2 520000 infinite
dev 1/0/0/1 40 5/35/0/40 (null) 310000 infinite

In this case the last line is taken into account.

There is a way to mitigate this by overriding what is retrieved from slurm so it is not critical, but that could be nice to combine the informations from the same partition to set the constraints/information.
