Systemd units, limits, and bin path fixes * Add restart for weave service unit * Reuse docker_bin_dir everythere * Limit systemd managed docker containers by CPU/RAM. Do not configure native systemd limits due to the lack of consensus in the kernel community requires out-of-tree kernel patches. Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com>
