Disable cri plugin by default in containerd and
allows an option to enable the plugin. This only
has an effect on containerd when supervised by
dockerd. When containerd is managed outside of
dockerd, the configuration is not effected.

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`:

```
when running `dockerd --log-level=panic`
```

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