regression in kes server command

[gutmensch]

Bug describtion

Latest build does not start kes server anymore and is always showing usage, no matter what parameters I add or remove (e.g. addr, auth, config).

    Command:
      /bin/sh
      -ce
      /entrypoint.sh kes server --config /config.yml --addr 0.0.0.0:7373 --auth on

Usage:
    kes server [options]

Options:
    --addr <IP:PORT>         The address of the server (default: 0.0.0.0:7373)
    --config <PATH>          Path to the server configuration file

    --key <PATH>             Path to the TLS private key. It takes precedence over
                             the config file
    --cert <PATH>            Path to the TLS certificate. It takes precedence over
                             the config file

    --auth {on|off}          Controls how the server handles mTLS authentication.
                             By default, the server requires a client certificate
                             and verifies that certificate has been issued by a
                             trusted CA.
                             Valid options are:
                                Require and verify      : --auth=on (default)
                                Require but don't verify: --auth=off

    -h, --help               Show list of command-line options

Starts a KES server. The server address can be specified in the config file but
may be overwritten by the --addr flag. If omitted the IP defaults to 0.0.0.0 and
the PORT to 7373.

The client TLS verification can be disabled by setting --auth=off. The server then
accepts arbitrary client certificates but still maps them to policies. So, it disables
authentication but not authorization.

Examples:
    $ kes server --config config.yml --auth =off

Expected behavior

Correct startup behaviour with image before latest release.
