This series is extracted from #7913 as it may prove useful to other series as well, and #7913 might take a while until its merged, given that it also depends on other unmerged pull requests.
The idea of this series is to move timeouts to the client state, which will allow changing them independently for each session - e.g. by setting per-service-level timeouts and initializing the values from attached service levels (see #7867).
Closes#8140
