Description

Currently, the Thread Context Map looks like this in JSONLayout:

Current

 "Properties":[
      {
        "name":"UserName",
        "value":"admin"
      },
      {
        "name":"OrgName",
        "value":"test"
      } 
    ] 

This does not properly make use of the JSON data format. Since the Thread Context Map is a map, it should be represented as a JSON object. And why not name it "mdc" rather than the quite vauge "Properties"?

Suggested

  "mdc": {
    "UserName":"admin", 
    "OrgName":"test"
  }
