Summary0033141: Change transaction mode to try server one by one and not broadcast the transaction
DescriptionThe current transaction mode broadcasts a message to all eligible servers. This can be okay and robust but gives rise to all kinds of race conditions when replicating transactions from one server to another.

A more safe/better controllable approach seems to be to only send a transaction to the first eligible server.

This also fits better to the concept of offline mode which corresponds to no server being available for a message. This is better than the current approach where we say that if one main server is not reachable that the user is in offline mode.
Steps To ReproduceCreate an environment with 2 servers
Create a ticket and check that it is broadcast to both servers at the same time

Proposed SolutionOnly send a message to the first online server which can receive it. If a server is not online then retry it several times and then retry a next available server.

The message stays in the database until it can be send to at least one of the servers.

Fixes issue 33141: Change transaction mode to try server one by one and not broadcast the transaction
Use fail over mode for transactional message, keep it in the database to retry, show offline always if there is at least one message to sync irrespective of server.
