Don't log config as warning in kuberpult-frontend-service

[Frank-Reichenbach]

The kuberpult-frontend-service prints the configuration on startup in the logs as a warning:

{
    "level":"warn",
    "ts":<timestamp>,
    "caller":"cmd/server.go:135",
    "msg":"config:
        {
            kuberpult-cd-service:8443
            false
            kuberpult-rollout-service:8443
            http://kuberpult-cd-service:80
            false
            https://<argocd-host-name>
            /keyring/keyring.gpg true

            <client-id>
            <tenant-id>
            https://<kuberpult-host-name>
            false
            v2.21.1
            master
            https://<kuberpult-host-name>
            <git-user-name>
            <git-user-email>
            2m0s
            10m0s
            false
            false
        }",
}

Since there is no information about the cause for a warning, I assume it is only informational and thus should be logged as "INFO" instead.
