OCTRL-1078 Make Task Controller able to control OCC tasks

[justonedev1]

introduction of controller for kubernetes inside the controller-operator folder.

This version allows us to control all OCC tasks (tested on readout, stfsender and stfbuilder). Currently there is not image and controller was run directly via make run on the node where the kubernetes cluster is running. If you run it locally and cluster is on different computer, you would not be able to communicate with OCC process as these require opened ports
Manifests required to run these tasks are inside the ecs-manifests subfolder.

In order to apply these manifests use kubectl. There is an explanation which file is which inside the kubernetes-ecs.md.

thanks! I did not try to run it yet, but I already have some questions/suggestions.

aah, we don't need any changes to the file, but it's auto-generated with the file name including the host name, am I correct?

[justonedev1]

yes, the argument is autogenerated by ansible during flp-suite deployment... But as far as I know (I haven't tried this) you can just pass config file to readout and it will be fine. .. The file in question http://mtichak-ost.cern.ch:8500/ui/alice-o2-cluster/kv/o2/components/readout/ANY/any/readout-stfb-mtichak-ost/edit doesn't contain any generated snippets as far as I can say. So we might probably be fine to store it in the repo and make the example args containing the path of this config file.

ah, I can get around consul with following: https://kubernetes.io/docs/concepts/configuration/configmap/

[justonedev1]

I added shm arguments to all kubernetes examples and used configMap for kubernetes, which creates config image in /etc/readout/readout-config.ini
