Load the credentials configuration from the config-security.yaml file

[developerhelperhub]

As security, we have to configure all credentials of api gateway services in the 'config-security.yaml' file instead of 'config.yaml' file. This helps to key security file to store into secret vault in the Kubernetes service, `config.yaml' configuration can be configured in the config-map in the Kubernetes service

Acceptance Criteria

• Load the 'mongo db' and 'openid' credentials in the 'config-security.yaml' file
• Load the configuration from 'config.yaml' file if the 'config-security.yaml' file not found

[developerhelperhub]

Implemented the following functionality

• Default configuration loaded from 'config.yaml' file
• Load the configurations from `configu-security.yaml' file
• Override the configurations from config.yaml file if the configuration present in the `configu-security.yaml' file

Example config.yaml

mongodb:
  host: localhost
  port: 27017
  db: klight-api-gateway
  connection_pool_size: 1

openid:
  discovery_url: "http://127.0.0.1:8084/realms/klight-api-gateway/.well-known/openid-configuration"
  validate_scope: false
  flow_type: introspection
  introspection_endpoint: "http://127.0.0.1:8084/realms/klight-api-gateway/protocol/openid-connect/token/introspect"

Example config-security.yaml

mongodb:
  username: klight-api-gateway
  password: klight-api-gateway

openid:
  client_id: klight-api-gateway-openid-connect
  client_secret: TYxTbrLzFagelYymONmgmSVfueiJnckT
