k0s reset: don't use crictl as a dependency

[jewertow]

Signed-off-by: Jacek Ewertowski jacek.ewertowski1@gmail.com

Issue
Fixes #743

What this PR Includes

1. Custom implementation of crictl commands.
2. Removal of embedded crictl.

How to test this change

1. Run k0s:

k0s install controller --enable-worker
systemctl start k0scontroller

2. Wait for k0s pods to be ready. There should be 6 pods:

systemctl status k0scontroller
k0s kubectl get pods -n kube-system

3. Stop k0s and reset:

systemctl stop k0scontroller
k0s reset --debug

All containers should be stopped and removed successfully.

@jewertow can you fix the build so we can proceed with the review

[jewertow]

@jasmingacic it seems to be a random failure. Are you able to rerun failed CI plan or do I have to trigger CI by empty commits?

[jasmingacic]

@jewertow I re-ran it and it failed again. No need to push any more commits.

Can you run the same tests locally?

[jewertow]

This test fails when I run it locally due to:

docker pull footloose-alpine
Using default tag: latest
Error response from daemon: pull access denied for footloose-alpine, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

#788 fixed flakiness of the tests. Could you rebase your PR so this gets cleared up

[jewertow]

@jasmingacic I rebased, but it failed once again. Could you rerun this step? As you saw before, it was working after a retry.

[jasmingacic]

Ok it is passing now you have to fix the conflicting file :)

[jasmingacic]

The code is looking good. Once the conflict is resolved I will have it approved

[jewertow]

@jasmingacic I rebased PR and fixed conflicts. All checks have passed.

[jasmingacic]

@trawler can you take a look too

[trawler]

lgtm! 👍
