[Health-dev] Add code in exceptions and warnings

[Luis Falcon]

Dear community

We're working on the upcoming GNU Health HMIS 4.0 component, and I
thought of introducing a code associated to each warning and error
message.

I think that, although most messages are self-explanatory, a unique
identifier would help for:

* Having a glossary of error messages, causes and their solutions
* Remove ambiguity in translations.

For example, the message
"No health professional associated to this user"

Could become
"No health professional associated to this user (E: health-055)"

The prefix would be the name of the package (health, health_imaging,
..) and the first letter will indicate the type of message (E:error,
W:warning...)

Let me know your thoughts.

Bests
Luis
