add a test suite for hearth

[bradsawadye]

This adds a test for a case where a patient, an encounter and procedures are created sequentially. This is so we test hearth under different conditions

IHS-130

@bradsawadye this build is failing due to linting issues that need to be resolved first

@bradsawadye should these comments still be addressed?

@bradsawadye so a slight change in how these two flow tests should be run. Lets set their config options to be the same for both as they are doing exactly the same flow, just in a different way.

This way we can more accurately compare the performance difference between the two tests

export const options = {
  stages: [
    { duration: '30s', target: 100 },
    { duration: '1m' },
    { duration: '30s', target: 0 }
  ],
  thresholds: {
    http_req_duration: ['p(95)<1000']
  },
  noVUConnectionReuse: true,
  discardResponseBodies: false
}
