What changes are included in this PR?

1. Log monitoring supports json logs，the parse type must be set to json

example:

{"time":"2023-03-23 16:19:01","level":"INFO","cost":1}

{
  "select": {
    "values": [
      {
        "as": "count",
        "agg": "count"
      },
      {
        "as": "cost_sum",
        "agg": "sum",
        "elect": {
          "type": "refName",
          "refName": {
            "name": "$.cost"
          }
        }
      }
    ]
  },
  "from": {
    "type": "log",
    "log": {
      "path": [
        {
          "type": "path",
          "pattern": "/tmp/1.log"
        }
      ],
      "charset": "utf-8",
      "parse": {
        "type": "json"
      },
      "time": {
        "_doc": "将 type 设置成 processTime 表示使用 '处理时间' 作为时间戳 ",
        "type": "elect",
        "elect": {
          "type": "refName",
          "refName": {
            "name": "$.time"
          }
        },
        "format": "golangLayout",
        "layout": "2006-01-02 15:04:05"
      }
    }
  },

          "refName": {
            "name": "$.level"
          }
        }
      }
    ]
  },
  "window": {

  },
