[Feature] Variables Definitions

[DisasteR]

Allow definition of variables to be reused in all the configuration.

Look at https://github.com/gazpachoking/jsonref It allow ref expansion.

ex :

{
  "easyucs": {
     "variables": {
         "password": "supersecurepassword",
         "anothervar": "myothervar",
     },
     ...
  },
...
"pasword" :  {"$ref": "#/easyucs/variables/password"}
...

for simplicity i have not encapsulated "variables" dictionary in a list.

variables can be expanded just before calling _validate_config_from_json responssible of json schema validation.

Sounds like an easy way to implement variables indeed. I'll have a look and keep you posted
