Add resource request form
This ticket may need to be refined once this is ready to be worked on.
Add resource request form after user has picked the resource type and VO they want to request resources for:
- Add ability to choose policy in case multiple policies match
- Add dynamic form for filling-in parameters set by the resource type
- Show validation errors in the form
- Add checkbox for privacy/legal things (TBD)
- Once the user completes the form a resource request is created in the DB and sent to the HCA
