             Summary: Update CM service discovery with the enhanced role 
configs endpoint
                 Key: KNOX-3084
                 URL: https://issues.apache.org/jira/browse/KNOX-3084
             Project: Apache Knox
          Issue Type: Task
          Components: cm-discovery
    Affects Versions: 2.1.0
            Reporter: Tamás Marcinkovics
            Assignee: Tamás Marcinkovics


There is a new CM API endpoint to fetch all role configurations for a given 
service ({{RolesResouce.readRolesConfig}}) if the supported API version is 
greater than or equal to v57. This endpoint is available in the 
cloudera-manager-api-swagger:7.13.1 artifact.

[https://repository.cloudera.com/service/rest/repository/browse/cloudera-repos/com/cloudera/api/swagger/cloudera-manager-api-swagger/7.13.1/]

On the Knox side, we need to change the existing {{readRoles}} and 
{{readRoleConfig}} API calls to the new {{readRolesConfig}} call.
The {{view}} parameter should still remain {{full}} as 
{{full_with_no_health_check}} only returns role configuration parameters with 
non-default values.
As the new cloudera-manager-api-swagger artifact is using okhttp 4.10, we also 
need to change {{DiscoveryApiClient}} setup and our Okhttp interceptors from 
Okhttp 2.7.5 to Okhttp 4.
