[Feature request] Signed configure

I do understand that the configure service uses the deployment mechanism to apply the configuration and therefore can not work when signed artifacts are activated.

A nice way to overcome this problem would be a field where one can drop a signed json config that gets then sent to the server.

It can work if you make and sign the artifact yourself. IIRC the build line goes something like this:

mender-artifact write module-image \
    -T mender-configure \
    -t raspberrypi4 \
    -n my-artifact \
    -k <SIGNING_KEY> \
    -m <JSON_CONFIG_FILE>

Not quite as convenient as what your proposed, but possible.
