6e24d33517 [runit integration] give a bit of time to start the service
Currently, we run sv start immediately after linking the service.
The runsv process may not be up at the moment, as a result of which
openrc will mark the service as stopped, even though it may be brought up
by runit at the next scan.

This is documented in the gentoo wiki:
https://wiki.gentoo.org/wiki/Runit#OpenRC.27s_runit_integration_feature

This PR adds a timeout so that correct process state can be reported.

Before:
 * Starting netdata-runit ...
fail: /run/openrc/sv/netdata: runsv not running
 * Failed to start netdata-runit

After:
 * Starting netdata-runit ...
fail: /run/openrc/sv/netdata: runsv not running
ok: run: /run/openrc/sv/netdata: (pid 9042) 0s

This fixes #253.

d87f5b2f24 rc-mount: make timeout invocation compatible with busybox timeout
Busybox timeout does not support the `-k` flag. As such, invoking fuser
from do_unmount never worked without this patch. This went unnoticed as
standard error is redirected to /dev/null. This patch fixes this by
simply removing the incompatible `-k` flag.

[Ariadne: the `-k` is redundant anyway, since we are sending the KILL
 signal to begin with.]

533a8c70b3 cgroup2_set_limits: fix harmless error message
In legacy cgroups mode, we were running `mountinfo -q ""` which was
generating an error message. If we return immediately when
cgroup2_find_path returns an empty value, we avoid this message.

87cfad3d6c cgroup2_set_limits: verify that the cgroup2 path is a mount point
prior to cgroups getting mounted, /sys/fs/cgroup will still exist,
but attempts to make directories in it will fail, change cgroup2_set_limits() to
verify that cgroups are mounted instead of just checking that /sys/fs/cgroup
exists.

5427783fdf standardize the default shell
I do not know of a need to have the default shell be a build-time
configurable setting. All *nix systems I am aware of have /bin/sh as a
default posix compatible shell.
If some systems running OpenRC do not make that assumption about
/bin/sh, I will consider bringing this back, so feel free to open an
issue.

af70862a7a supervise-daemon: use a default pid file if one is not specified
Since the pid file is internal to us, start moving toward deprecating it
by not requiring the user to specify it.
In the next release, I plan on working on code to start phasing out the
use of a pid file if this is possible.

16ff3cd8df check whether /sys/fs/cgroup is a mountpoint
The current check only tries to detect whether /sys/fs/cgroup exists and
whether it is writable or not. But when the init system doesn't mount
cgroups then /sys/fs/cgroup will just be an empty directory. When paired
with unprivileged containers that mount sysfs this will cause misleading
errors to be printed since /sys/fs/cgroup will be owned by user
nobody:nogroup in this case. Independent of this specific problem this
check will also be misleading when the /sys/fs/cgroup exists and is in
fact writable by the init system but isn't actually a mountpoint.

Note from William. "grep -qs" doesn't need to redirect output to
/dev/null since it is completely silent.

This fixes #209.

Add the following variables to expose more arguments that can be passed
to start-stop-daemon or supervise-daemon:

- directory will be passed to --chdir
- error_log will be passed to --stderr
- output_log will be passed to --stdout
- umask will be passed to umask
