[masakari] Deprecating process monitor - querying the community in this thread

Hello users of Masakari, As the Masakari core team, we have discussed the deprecation/retirement of one of the monitors - the process monitor. The reason is simple - we consider its mission is better handled by other software such as Kubernetes, Docker, or systemd, depending on how you deploy your OpenStack cluster. I believe the process monitor might have made sense in the pre-containerisation, pre-systemd world but it does not seem to any longer. Please let us know, by replying to this mail, if you have a use case for the process monitor that cannot be handled by the aforementioned software. -yoctozepto
