Bug Description
In large and high density deployment, ceph daemon hits pid limit. Recently upstream has added a description regarding kernel.pid_max in their doc.
It would be great if ceph charms add kernel.pid_max values into the deployed nodes to be capable of handling large and high density deployments.

> Hosts with high numbers of OSDs (e.g., > 20) may spawn a lot of threads, especially during recovery and rebalancing. Many Linux kernels default to a relatively small maximum number of threads (e.g., 32k). If you encounter problems starting up OSDs on hosts with a high number of OSDs, consider setting kernel.pid_max to a higher number of threads. The theoretical maximum is 4,194,303 threads. For example, you could add the following to the /etc/sysctl.conf file:
>
> kernel.pid_max = 4194303
