This PR is a POC for storing config parameters in Config table - related PR https://github.com/opentorc/platform-api/pull/1133 - added two methods to the cli to be able to test it.

1. Create Config table mentioned in the related PR
   1.a Creat SSM variable DYNAMODB_CONFIG_TABLE under common path

2. install config-wrapper package locally npm i path../.../config-wrapper

3. create sharedConfig.json
   eg

{
  "DYNAMODB_USER_TABLE_STREAM": {
      "value": "TABLE_NAME"
  },
  "ASSESSMENT_CONFIG": {
     "value":  {
              "testId": 123459,
              "valir": false
     }
  },
  "ARRAY_CONFIG" : {
    "value": [{
      "testValue" : 5
    }]
  }
}

5. with the cli create service parameters config-wrapper putSharedConfigFromFile --infile sharedConfig.json --env develop --service resolvers

6. with the cli get service parameters config-wrapper getSharedConfigByService --env develop --service resolvers

NOTE: When configWrapper.awsManager.getSharedConfigByService() method is called in a lambda function. Lambda function should have dynamodb:Query permission for the Config_Table including Config_Table/index/*

Test is same as the one before - to test if cached value returned, you would need to first retrieve the values, then update them - and then retrieve them again to verify that you are NOT getting the updated value... thus proving that it is indeed read from cache.

However, you don't have to write such a test right now. So you can remove this one.
