[Enhancement] Review workspace as output placeholder

[adrianriobo]

This is an opinionated way to define how wokspaces should maintain the host information to be used by other tasks.

Typically we use a secret structure which can be represented as a workspace:

- name: host-info
  description: |
    ocp secret holding the hsot info credentials. Secret should be accessible to this task.
