#915 Add commands and procedures to procedure creation

Adds the possibility to create a procedure with commands and other
procedures integrated as steps.

Note: "steps" parameter is optional and "steps" array object order
defines execution order.

Request:
POST /procedure/add
{
  "center": "1",
  "name": "procedure",
  "description": "My procedure",
  "steps": [
             {
               "command": "wol",
               "params": { "type": "broadcast" }
             },
             {
               "procedure": 22
             },
             {
               "command": "poweroff",
               "params": {}
             }
           ]
}
