Intermittent 401 unauthorised in integration tests

[jwulf]

"Randomly", a test will fail in the suite with a 401 Unauthorised response from an API.

Example:

 console.log
    Failed to search for process instances for 2251799813685806

      at src/zeebe/lib/cancelProcesses.ts:16:12

  console.log
    HTTPError: Response code 401 (Unauthorized) (request to http://localhost:8081/v1/process-instances/search)
        at Request.<anonymous> (/Users/jwulf/workspace/c8-sdk/node_modules/got/dist/source/as-promise/index.js:118:42)

This is probably due to an expired token being used for the request.

To debug this, I'll need to write a lifecycle unit test for the OAuth token expiry strategy.

Instead, I increased the token refresh threshold to 10s on SaaS. Let's see if this fixes it. Will reopen if it reoccurs.
