Add disk space directive which scales with task attempts

[rcannood]

We could create separate disk labels:

  withLabel: lowdisk { disk = { 20.GB * task.attempt } }
  withLabel: middisk { disk = { 50.GB * task.attempt } }
  withLabel: highdisk { disk = { 100.GB * task.attempt } }
  withLabel: veryhighdisk { disk = { 200.GB * task.attempt } }

To src/workflows/utils/labels.config

And add it to components where needed
