odo Pull application from cluster (Devfile as a ConfigMap in the cluster)

Pull application from cluster (Devfile as a ConfigMap in the cluster)

As on odo user
I want to be able to import/pull application running on the cluster (I don't have it's devfile, and I don't know where the source code is)
So that I can make changes to the application and run it with my changes

[ ] It should sync the Devfile content to a ConfigMap in the cluster ~~- [ ] It should watch for changes to this ConfigMap and handle them in its reconcile loop~~
[ ] This ConfigMap should be the parent Kubernetes owner object of all the other objects odo creates (Deployments, Services, ...)
[ ] This ConfigMap should be used whenever we need to retrieve all Kubernetes objects that pertain to the Devfile
[ ] Leave room for extension in the ConfigMap spec
[ ] Make sure the naming scheme allows to store this in a shared namespace. Naming scheme should be consistent with what will be done in https://github.com/redhat-developer/odo/issues/5862
[ ] Update odo delete logic to use this
[ ] Make sure Devfile changes are handled even if the devfile.yaml is Git-ignore'd. For example, changes to the commands in the Devfile should cause the commands to be restarted in the container. See https://github.com/redhat-developer/odo/pull/5933#issuecomment-1204880533
[ ] It should also not break the --no-watch flag

side effect odo codebase could be simplified (e.g., ownerReferences / deletion handling, selecting all dependent resources)

~~- Use new approach based on reconcile loop POC: https://github.com/feloy/odo-dev-controller-poc~~
