Improve Datasource representation about historical-datastore HOT 3 CLOSED

Proposal:

Remove "id" and rename "resource" to "name".

How it would change the API:

Registry:

/registry/name/with/slash

/registry/filter/type/path/op/value

Data:

GET /data/name/with/slash

GET /data/encoded_name_1, encoded_name_2

POST /data 

from historical-datastore.

The new format is as follows:

     {
      "name": "c5/1/kitchen/coffee-tablet/power",
      "source": {
        "type": "MQTT",
        "url": "tcp://mqtt.eclipse.org:1883",
        "topic": "c5/1/kitchen/coffee-tablet/power"
      },
      "dataType": "float",
      "meta": null,
      "retain": {
         "min":"1w",
         "max":"1y"
      }

from historical-datastore.
