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.

[knopers8]

why is the manifest file added as an argument to readout?

[justonedev1]

it is described in the documentation, basically it is a scaffold to let the executor know which manifest to load. You can see it inside the KubectlTask in other PR

[knopers8]

indeed, saw it there, clear. perhaps you could add a yaml comment to avoid confusion.

[knopers8]

Perhaps this and the other manifest in this directory could be moved to ecs-manifests.

[justonedev1]

this is leftover

[knopers8]

do you plan to remove it then?
