Fix cps ran yang data model

* Add a liquibase change set to update cps ran model data
* Rename model "cps-ran-schema-model@2021-01-28.yang" to
  be compliant with yang specifications related to file layout
  https://tools.ietf.org/html/rfc7950#section-5.2
* Improve yang validation error handling to provide more information
  about the validation failure in the request response
* Add csit test to verify cps ran model retrieval
