[COMMON] Add job support for readinessCheck

readinessCheck was only supporting "container" readiness and not "job"
readiness.
This patch adds the ability to wait for job readiness also.

for that, we need to use the "extended" version and set type to `job` as
we can see it the example:

```yaml
wait_for:
  name: myname
  jobs:
    - '{{ include "common.release" . }}-the-job'
```
