GPU runOptions suggestions

[an-altosian]

Description of feature

Hi there,

Currently the GPU profile is written as

gpu {
        docker.runOptions       = '-u $(id -u):$(id -g) --gpus all'
        apptainer.runOptions    = '--nv'
        singularity.runOptions  = '--nv'
    }

I suggest to append the GPU related args to the runOptions instead of overwriting them. So, I suggest to change to

    gpu {
        docker.runOptions       = (docker.runOptions ?: '') + ' --gpus all'
        apptainer.runOptions    = (apptainer.runOptions ?: '') + ' --nv'
        singularity.runOptions  = (singularity.runOptions ?: '') + ' --nv'
    }

Best,
Dongze
