API: Restricted Files & Terms of Access in the dataset

[ChengShi-1]

Overview of the Feature Request
For edit dataset terms, we have a section Restricted Files + Terms of Access applying for all files in a dataset.

• restricted/unrestricted files with terms of access
  • with following fields

TermsOfAccess {
  fileAccessRequest: boolean
  termsOfAccessForRestrictedFiles?: string
  dataAccessPlace?: string
  originalArchive?: string
  availabilityStatus?: string
  contactForAccess?: string
  sizeOfCollection?: string
  studyCompletion?: string
  termsOfUse?: string
  confidentialityDeclaration?: string
  specialPermissions?: string
  restrictions?: string
  citationRequirements?: string
  depositorRequirements?: string
  conditions?: string
  disclaimer?: string
}

• an update of terms of access to dataset metadata related api results is also needed

For restricted files, we have an api restrict files, only works for a single file.
However, in the description, it said

Note that some Dataverse installations do not allow the ability to restrict files (see :PublicInstall).
We may still need the API, but disallow it in the setting

What kind of user is the feature intended for?
(Example users roles: API User, Curator, Depositor, Guest, Superuser, Sysadmin)
API User

What inspired the request?
IQSS/dataverse-frontend#799

@ChengShi-1 do we need this to handle the dataset license as well?
