Configuration parameters for OAuth2 token URLs incorrectly named issuer URLs

[holger-stenzhorn]

The parameters to configure OAuth2 token URLs are incorrectly named issuer URLs in mii-process-data-sharing, mii-process-data-transfer and mii-process-report, i.e.

• DE_MEDIZININFORMATIK_INITIATIVE_DATA_SHARING_DIC_FHIR_SERVER_OAUTH2_ISSUER_URL (de.medizininformatik.initiative.data.sharing.dic.fhir.server.oauth2.issuer.url)
• DE_MEDIZININFORMATIK_INITIATIVE_DATA_SHARING_DMS_FHIR_SERVER_OAUTH2_ISSUER_URL (de.medizininformatik.initiative.data.sharing.dms.fhir.server.oauth2.issuer.url)
• DE_MEDIZININFORMATIK_INITIATIVE_DATA_TRANSFER_DIC_FHIR_SERVER_OAUTH2_ISSUER_URL (de.medizininformatik.initiative.data.transfer.dic.fhir.server.oauth2.issuer.url)
• DE_MEDIZININFORMATIK_INITIATIVE_DATA_TRANSFER_DMS_FHIR_SERVER_OAUTH2_ISSUER_URL (de.medizininformatik.initiative.data.transfer.dms.fhir.server.oauth2.issuer.url)
• DE_MEDIZININFORMATIK_INITIATIVE_REPORT_DIC_FHIR_SERVER_OAUTH2_ISSUER_URL (de.medizininformatik.initiative.report.dic.fhir.server.oauth2.issuer.url)

This is even more problematic as the respective parameter in mii-process-feasibility correctly sets the issuer URL (and not the token URL), i.e. DE_MEDIZININFORMATIK_INITIATIVE_FEASIBILITY_DSF_PROCESS_CLIENT_STORE_AUTH_OAUTH_ISSUER_URL (de.medizininformatik_initiative.feasibility_dsf_process.client.store.auth.oauth.issuer.url)

The two solutions could be either:

1. Rename the parameters to ..._OAUTH2_TOKEN_URL (...oauth2.token.url)
2. Handle the parameters really as issuer URLs and not as token URLs

Solution 2 should be preferred to be consistent with the feasibility process.
