batch connect selection defaults

[johrstrom]

From discourse - https://discourse.openondemand.org/t/batch-connect-form-field-defaults/3209

Basically this feature is to provide a mechanism so folks can

• reset the form to defaults (disregarding what has been cached)
• provide a checkbox that reads something like remember my selections that can disable caching altogether.
• display the default values inside the field when the field is blank

One technical issue I see with this is providing defaults. Defaults are provided when the form is rendered on the server side, not the client side. So somehow the HTML has to retain what the default should be for the user to reset it back to. I.e., the form is rendered with the last cached setting, so how does the client know what the default was because the current value is from the cache?

I should also note that this ticket may be split up as it's a few different things.
