Warning thrown when using self-signed certificates

[emzet]

There is the guide about using self-signed certificates. When one runs provided command:

docker run \
  --rm \
  -v ${YOUR_CERTS_DIR}/cacerts:/tmp/cacerts \
  -v ${YOUR_REPO}:/usr/src \
  -e SONAR_HOST_URL="http://${SONARQUBE_URL}" \
  sonarsource/sonar-scanner-cli

got this warning message:

Warning: use -cacerts option to access cacerts keystore

Besides that, everything works as it should.
