Containerd Config file path is now tweakable

[bbourbie]

Some containerd shims can be installed via daemonSets. (eg. katacontainers)

Usually, these daemonsets add the shims and modify the containerd config file on the fly by adding the necessary parameters for their shims.

Example of such code https://github.com/kata-containers/kata-containers/blob/main/tools/packaging/kata-deploy/scripts/kata-deploy.sh

The config file path is usually at /etc/containerd/config.toml but kops has set the path to /etc/containerd/config-kops.toml

I felt it was necessary to add that option because changing the config file path to the regular path could have been seen as breaking change.

Hi @bbourbie. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@bbourbie The config file name is a relic from the times when kOps installed containerd from deb/rpm. Renaming the config file to config.toml was something I was planning to do sooner or later so should be fine to do that instead. The config file path should still be added in case someone wants the backwards compatibility. The new option should be added also to the v1alpha2 and v1alpha3 API versions and then run make crds and make apimachinery.

@olemarkus Any thoughts?

All of that makes sense to me.
