This patch adds support for modifying settings for the default cgroups;
init, user, and system, as well as adding up to a total of eight groups
for the system.
Services can now be assigned to a cgroup, with optional extra settings
for that particular process group. The syntax is slightly contrivied
but follows the overall Finit syntax of prop:value,prop':value', e.g.
cgroup maint cpu.weight:123,mem.max:10000
Starting with the introduction of rlimits, a group of services sharing
the same .conf file can share the same (locally "global") rlimits, and
now also the same cgroup, e.g.
cgroup.maint
service foo
service bar cgroup:mem.max:1000
This puts foo and bar in the same top-level cgroup 'maint', with an
extra memory restriction on bar for max 1000 bytes memory.
NOTE: 'mem.' is a Finit extension, a shorthand for cgroups2 'memory.'
