[DataStorage] Request Rejection from localhost and 127.0.0.1

[tiokim]

Describe the issue
DataStorage rejects localhost and 127.0.0.1 requests other than the IP set as Service's Host in configuration.toml.

To Reproduce

1. Run Edge Orchestration with edgex
2. Requests to Edge Orchestration DataStorage

• curl -X POST "127.0.0.1:49986/api/v1/resource/int" -H "accept: text/plain" -H "Content-Type: text/plain" -d 1
• curl -X POST "localhost:49986/api/v1/resource/int" -H "accept: text/plain" -H "Content-Type: text/plain" -d 1

t25kim@t25kim:~/work/edge-home-orchestration-go$ curl -X POST "10.113.70.227:49986/api/v1/resource/int" -H "accept: text/plain" -H "Content-Type: text/plain" -d 123
t25kim@t25kim:~/work/edge-home-orchestration-go$ curl 10.113.70.227:49986/api/v1/resource/int

t25kim@t25kim:~/work/edge-home-orchestration-go$ curl -X POST "127.0.0.1:49986/api/v1/resource/int" -H "accept: text/plain" -H "Content-Type: text/plain" -d 1
curl: (7) Failed to connect to 127.0.0.1 port 49986: Connection refused

curl: (7) Failed to connect to localhost port 49986: Connection refused

Expected solution

• Request EdgeX to open up to localhost and 127.0.0.1

Alternative

• Create a REST API that returns service host information at externalhandler
