Change what returns in response <<status>> when &fullperiodicals=false

Current implementation

• If the resource is a serial/periodical and &fullperiodicals=false OR &fullperiodicals is not included on the GET edge-rtac response THEN <<status>> returns a holdings statement IF there is only one holdings statement
  AND if there are multiple holdings statements then Multi is returned as status (see screenshot below)

Requirement

• IF holdings information is only returned THEN return <status>Holdings information only</status> in the response
  <?xml version='1.0' encoding='UTF-8'?>
  <instances>
  <holdings>
  <instanceId>f91f640e-af79-499b-a507-01db768b919f</instanceId>
  <holding>
  <id>e957c3a3-617e-4bd1-846a-443a13dcfcda</id>
  <callNumber>HB171</callNumber>
  <location>Full Text</location>
  <status>Holdings information only</status>
  </holding>
  </holdings>
  </instances>

Acceptance criteria

• Verify this update with batch parameter and without batch parameter
• Verify this update with fullPeriodicals=true, fullPeriodicals=false, and without the parameter included
  • There should be no change to the rtac response when &fullperiodicals=true. Change only applies when &fullPeriodicals=false, and without the parameter included
• Verify no impact to performance
