TLS certificate verification doesn't always work as expected

Artillery does not always recognize valid TLS certificates. For example:

$ artillery quick -d 10 -r 5 https://artillery.io

  Scenarios launched: 49
  Scenarios completed: 0
  Number of requests made: 0
  RPS: 4.73
  Request latency:
    min: Infinity
    max: -Infinity
    median: NaN
    p95: NaN
    p99: NaN
  Scenario duration:
    min: Infinity
    max: -Infinity
    median: NaN
    p95: NaN
    p99: NaN
  Errors:
    UNABLE_TO_VERIFY_LEAF_SIGNATURE: 49

The issue is that Node.js uses its own certificate bundle, which does not include many CAs. To fix, a custom bundle needs to be used by the HTTP engine.

@vineyugave you can use -k flag to turn off certificate validation, like so: artillery run -k myscript.json
