Service Hijacking Mock Webservice

This is the mock webservice used in the Krkn Service Hijacking scenario. This webservice, based on Flask dinamycally loads a time-based test plan with the following syntax:

- resource: /list/index.php
  steps:
    GET:
      - duration: 15
        status: 500
        mime_type: application/json
        payload: |
          {
            "status":"internal server error"
          }
      - duration: 15
        status: 201
        mime_type: application/json
        payload: |
          {
            "status":"resource created"
          }
    POST:
      - duration: 15
        status: 401
        mime_type: application/json
        payload: |
          {
             "status": "unauthorized"
          }
      - duration: 15
        status: 404
        mime_type: text/plain
        payload: not found
- resource: /patch
  steps:
    PATCH:
      - duration: 15
        status: 201
        mime_type: text/plain
        payload: resource patched
      - duration: 15
        status: 400
        mime_type: text/plain
        payload: bad request

the webservice loads two environment variables:

• TEST_PLAN_PATH: (mandatory) is the path in the filesystem where the test plan is located. Krkn mounts it to the pod deployed using a ConfigMap
• STATS_ROUTE: (optional, default /krkn-stats) overrides the default route of resource that prints the chaos run statistics in case of a conflict with the test plan
