notes:
- The only security scheme declared anywhere in the 116 OpenAPI documents is oAuth2ClientCredentials, with a deployment
  supplied {tokenUrl}; 64 of the documents declare it. There are no API keys, no basic auth and no openIdConnect
  scheme in the estate.
- Tokens are issued by the NRF (TS 29.510 Nnrf_AccessToken) for 5G core service based interfaces, and by the CAPIF
  core function (TS 29.222, security architecture in TS 33.122) for northbound APIs consumed by third party application
  functions.
- Beyond the token, TS 33.501 and TS 33.122 require TLS between network functions and certificate based mutual authentication
  on the CAPIF-1e and CAPIF-2e reference points; that is specified in prose and is not expressed as a mutualTLS
  securityScheme in the OpenAPI.
- 3GPP itself issues no credentials. The token endpoint, client id and secret all come from the operator or exposure
  platform that deployed the interface.
