JCU/Add CitacePRO configuration (ported from customer/mendelu) (#1361)

* JCU/Add CitacePRO configuration (ported from customer/mendelu)

Adds the CitacePRO citation-service configuration required by the frontend
item-page citation widget:

- dspace.cfg: citace.pro.url, citace.pro.university, citace.pro.allowed.
  citace.pro.university is a FLAGGED PLACEHOLDER (dspace.jcu.cz) -- the real
  JCU CitacePRO-registered repository host must be confirmed with the customer.
- modules/rest.cfg: expose the three citace.pro.* properties via REST so the
  UI can read them through ConfigurationDataService.

Ported from dataquest-dev/DSpace #1210. The OAI-PMH oai_dc.xsl citation
formatting (#1233 / #1297 / #1312 / #1314) is intentionally NOT included: it is
metadata-schema-specific to mendelu (local.volume, local.number,
dc.relation.ispartof, dc.description.version) and will be applied separately on
JCU prod against JCU's own metadata schema.
