Result form(s) for labs

[jkleinsc]

Right now there is a generic result field for labs. At some point we should support generation of result forms like the following:

The same technology solution we need for #90 is what we need here. Form-builder capability.

@taras this is another example of where a configurable form component is needed.

This feature can be implemented by extending the custom forms feature to work with labs. This means doing the following:

1. Add a new form type to https://github.com/HospitalRun/hospitalrun-frontend/blob/master/app/admin/custom-forms/edit/controller.js#L77-L82
2. Modify https://github.com/HospitalRun/hospitalrun-frontend/blob/master/app/labs/edit/route.js to setup custom forms for new objects.

  customForms: inject.service(),
 
  getNewData() {
    let customForms = get(this, 'customForms');
    let newData = {
      customForms: Ember.Object.create()
    };
    return customForms.setDefaultCustomForms(['lab'], newData);
  },

3. Add the following to https://github.com/HospitalRun/hospitalrun-frontend/blob/master/app/labs/edit/template.hbs:

{{custom-form-manager model=model formType="lab"}}

This will allow custom forms to be created and added to lab results.
