data-set overrides previous cached values

[johrstrom]

related to #2817 - Disclaimer that this may be tricky and/or is an indication that something needs reworked fundamentally.

data-set- directives currently override previous cached values in the form. Consider this form.yml. It says I can have a max of 4 GPUs.

cluster:
  - owens

form:
  - gpus
  - node_type
attributes:
  gpus:
    widget: number_field
    min: 0
    max: 4
  node_type:
    - ['gpu', data-set-gpus: 1]
    - ['cpu', data-set-gpus: 0]

Now if I Submit the job with a selection of 2 GPUs.

expected behavior

When I reload the page, it should have cached the choice of 2 GPUs.

actual behavior

The data-set directive sets the gpu field to 1.

I open this because as a user it would be very frustrating to always have to change the value of gpus to 2 even though the choice should have been cached.
