 * master set-up on sap-p1-2 must be configured in "failover" mode by default; this means it sends to the local RabbitMQ and the security_service MongoDB replica set that does not replicate into the cloud, to keep traffic on the SSH tunnel to the cloud as low as possible
 * create a "primary master" configuration on sap-p1-2 in case sap-p1-1 fails for a longer time and we need to switch to sap-p1-2 for a longer time; in that case we would like to have DB replication into the cloud, so use the localhost:[10201|10202|10203] "paris2024" MongoDB replica set and send to the RabbitMQ in the cloud (rabbit-eu-west-3); these failover scenarios should be manageable by corresponding scripts
 * Shall we obtain the tunnel scripts via symbolic links from the respective git repo at /home/sailing/code, there then under configuration/on-site-scripts/paris2024/sap-p1-[12]? Currently, they are copies that evolve independently from the git repo.
