I can see two json files(host.json and local.settings.json) has been added in Azure Function directory.

### host.json

```json
{
    "version": "2.0",
    "logging": {
        "applicationInsights": {
            "samplingExcludedTypes": "Request",
            "samplingSettings": {
                "isEnabled": true
            }
        }
    }
}

```

### local.settings.json

```json
{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet"
  }
}

```

What is the purpose of having these two json files?
