This makes some changes to the maintainer's guide and roles within the
project. It removed the concept of a BDFL and carries over the chief
maintainer role into the project. BDFL sucks and we can do better and
these changed help to make many more things specific around adding new
maintainers and removing them as well.

Actually cgroup mounts are bind-mounts, so they should be
handled by the same way.

Sometimes subsystem can be mounted to path like "subsystem1,subsystem2",
so we need to handle this.

This is needed because for nested containers cgroups. Without this patch
they creating unnecessary intermediate cgroup like:
/sys/fs/cgroup/memory/system.slice/docker-9409d9f0b68fb9e9d7d532d5b3f35e7c7f9cca1312af392ae3b28436f1f2998f.scope/system.slice/docker-9409d9f0b68fb9e9d7d532d5b3f35e7c7f9cca1312af392ae3b28436f1f2998f.scope/docker/908ebcc9c13584a14322ec070bd971e0de62f126c0cd95c079acdb99990ad3a3
It is because in /proc/self/cgroup we see paths from host, and they don't
exist in container.

Before name=systemd cgroup was mounted inside container to
/sys/fs/cgroup/name=systemd, which is wrong, it should be
/sys/fs/cgroup/systemd

And allow cgroup mount take flags from user configs.
As we show ro in the recommendation, so hard-coded
read-only flag should be removed.

Before this, we got mount info in container:
```
sysfs /sys sysfs ro,seclabel,nosuid,nodev,noexec,relatime 0 0
/sys/fs/cgroup tmpfs rw,seclabel,nosuid,nodev,noexec,relatime 0 0
cgroup /sys/fs/cgroup/cpuset cgroup rw,relatime,cpuset 0 0
```
It has no mount source, so in `parseInfoFile` in Docker code,
we'll get:
```
Error found less than 3 fields post '-' in "84 83 0:41 / /sys/fs/cgroup rw,nosuid,nodev,noexec,relatime - tmpfs rw,seclabel"
```
After this fix, we have mount info corrected:
```
sysfs /sys sysfs ro,seclabel,nosuid,nodev,noexec,relatime 0 0
tmpfs /sys/fs/cgroup tmpfs rw,seclabel,nosuid,nodev,noexec,relatime 0 0
cgroup /sys/fs/cgroup/cpuset cgroup rw,relatime,cpuset 0 0
```

- Initialize swappiness to -1 for the default config.json
- Pass swappiness from config.json to libcontainer config
