containers may specify these cgroup values at runtime. This will allow processes to change their priority to real-time within the container when CONFIG_RT_GROUP_SCHED is enabled in the kernel. See #22380. Also added sanity checks for the new --cpu-rt-runtime and --cpu-rt-period flags to ensure that that the kernel supports these features and that runtime is not greater than period. Daemon will support a --cpu-rt-runtime flag to initialize the parent cgroup on startup, this prevents the administrator from alotting runtime to docker after each restart. There are additional checks that could be added but maybe too far? Check parent cgroups to ensure values are <= parent, inspecting rtprio ulimit and issuing a warning.

The non-reference docs have been moved!
The documentation for Docker Engine has been merged into the general documentation repo.
See the README for instructions on contributing to and building the documentation.
If you'd like to edit the current published version of the Engine docs, do it in the master branch here: https://github.com/docker/docker.github.io/tree/master/engine
If you need to document the functionality of an upcoming Engine release,
use the vnext-engine branch:
https://github.com/docker/docker.github.io/tree/vnext-engine/engine
The reference docs have been left in docker/docker (this repo), which remains the place to edit them.
The docs in the general repo are open-source and we appreciate your feedback and pull requests!
