title: Authenticate postgrest api through keycloak
body: <p>Postgrest APIs can be secured through inbuilt JWT tokens or through a third party service like Auth0, Okta or Keycloak (<a href="http://postgrest.org/en/v5.0/install.html" rel="nofollow noreferrer">http://postgrest.org/en/v5.0/install.html</a>)</p>
