HA secrets.yaml should be used in conjuntion with Add-ons yamls

[helson22]

Hello again,

I tried to use the HA functionality coming with secrets.yaml with following log-error

(node:230) [TAG_RESOLVE_FAILED] YAMLWarning: Unresolved tag: !secret at line 20, column 9:
  user: !secret mqtt_u
        ^^^^^^^
(Use `node --trace-warnings ...` to show where the warning was created)
(node:230) [TAG_RESOLVE_FAILED] YAMLWarning: Unresolved tag: !secret at line 21, column 13:
  password: !secret mqtt_p

It is usefull for mqtt connection data such as (usr, pw, host-ip) and for cpu-ip adresse for example.

Is it possible to implement this in the add-on?

Thx alot!
