If Artillery is installed globally:

1. Set config.target to the name of the Lambda function
2. Specify additional options in config.lambda:
- region - AWS region (default: us-east-1)
3. Set the engine property of the scenario to lambda.
4. Use invoke in your scenario to invoke the Lambda function
5. Specify additional invocation parameters:
- payload - String or object with the payload to send to the Lambda function
- invocationType - Lambda invocation type. One of Event, RequestResponse, DryRun
- logType - One of None, Tail
- qualifier - Lambda qualifier
- clientContext - client context to pass to the Lambda function as context
- target - invocation specific target overriding global default in config.target.

#### Payload substitution
The Lambda payload can include variable and function placeholders in the form of {{ [VAR_NAME_OR_FUNC_CALL] }}.

For example the payload might include a call to the built-in Artillery functions $randomNumber(min max) or $randomString(length).

Use $contextUid() to get the scenario unique ID in your payload.
