Add REST API to deploy module
> Were you able to run this code successfully?

Testing that currently, the rest API end points are visible and `get` method works successfully. However, `post` method with /v1/completions/ end point is failing and I am debugging that.

Was able to run the code successfully with the /v1/completions/ endpoint. Here's the curl request sent and the output received.
```python
curl -X POST http://localhost:8080/v1/completions/ \
-H "Content-Type: application/json" \
-d '{
  "model": "LLama2-7B",
  "prompt": "Say this is a test",
  "max_tokens": 512,
  "temperature": 1.0,
  "top_p": 0.0,
  "n": 1,
  "stream": false,
  "frequency_penalty": 1.0
}'
```
```python
{"output":".\nSay this is a test. Say this is a test. Say this is a test. Say this is a test. Say this is a test. Say this is a test. Say this is a test. Say this is a test. Say this is a test.
