dockerd allows the `--log-level` to be specified, but this log-level
was not forwarded to the containerd process.
This patch sets containerd's log-level to the same as dockerd if a
custom level is provided.
Now that `--log-level` is also passed to containerd, the default "info"
is removed, so that containerd's default (or the level configured in containerd.toml)
is still used if no log-level is set.
Before this change:
containerd would always be started without a log-level set (only the level that's configured in `containerd.toml`);

After this change:
when running `dockerd` without options (same as current);

when running `dockerd --debug`:

```
combining `--debug` and `--log-level` (`--debug` takes precedence):

This fixes an issue where the containerd client is cached in a container
object in libcontainerd and becomes stale after containerd is restarted.

With the ticker this could end up just doing back-to-back checks, which
isn't really what we want here.
Instead use a sleep to ensure we actually sleep for the desired
interval.

Before this patch, when containerd is restarted (due to a crash, or
kill, whatever), the daemon would keep trying to process the event
stream against the old socket handles. This would lead to a CPU spin due
to the error handling when the client can't connect to containerd.
This change makes sure the containerd remote client is updated for all
registered libcontainerd clients.
This is not neccessarily the ideal fix which would likely require a
major refactor, but at least gets things to a working state with a
minimal patch.
