warn about impossible conditions

[teto]

Feature Request

warn if conditions can not be satisfied
Out of curiosity I added the following condition to a process (e.g, waiting for postgres to be up) wihout setting up a healthprobe on postgresql.

    depends_on:
      postgresql:
        condition: process_healthy

so it turns out that my process with never start.

Use Case:

avoid mistake/help the user write his configuration

Proposed Change:

It might be useful to add a warning in that case (in F3, the process details) or instead of pending mark as "Impossible". In the logs at least.

Who Benefits From The Change(s)?

On a related note, the doc says:

process_healthy - is the type for waiting until a process is healthy

does is mean ready & alive ? just ready ? Could be nice to explicit. It's maybe obvious for kubernetes administrators and as a basic kube user it's not obvious yet. Seems like in my tests it was the "ready" probe. In which case it could be called "process_ready" ?

Hey @teto,

Thanks for all the improvement recommendations.
I will add a better warning to the next release.
