Generalise base.configs

Base config is quite long at the moment with default resource settings for every process.

@maxulysse suggested to generalise the resources using labels.

i.e. in the base_config set the following

  withLabel:cpus_1 {
    cpus = {check_resource(1)}
  }

(https://github.com/nf-core/sarek/blob/4bdff8eed3e4bf1a4393b226d2e87f09c2346d35/conf/base.config#L22-L24)

And then in the main, add the label:

process FastQCFQ {
    label 'cpus_2'


    tag {idPatient + "-" + idRun}

Processes that still require very special resources (e.g. MALT) can still use the withName process selector
