axios-retry added to the calls to projects-api

1. Passing axios object to axiosRetry adds interceptors to axios globally. So, instead of calling axiosRetry each time under helper methods, it is enough to call it for 1 time in helper.js global area. Also for example, calling axiosRetry under ensureProjectExist method doesn't make it scpecific to that method but axiosRetry will be applied to all axios calls. (Other than v5/projects)
2. Please remove all axiosRetry calls and add it to the global area.
3. In retry condition we should check if the called url belongs to project api; e.config.url.indexOf('v5/projects') > 0 && (axiosRetry.isNetworkOrIdempotentRequestError(e) || e.response.status === 429)
4. Also we can add a logger to see if it was retried:

onRetry: (retryCount, error, requestConfig) => 
    logger.info(retryCount) // retry count and the called url can be logged here in a good format.
  

6. axiosRetry.exponentialDelay's initial delay seemed a bit less to me. We can tweak their function and use the following instead:

function exponentialDelay (retryNumber = 0) {
  const delay = Math.pow(2, retryNumber) * 200
  const randomSum = delay * 0.2 * Math.random() // 0-20% of the delay
  return delay + randomSum
}

7. Since you'll change the code now, let's revert the changes on helper.js and avoid changing lintings.
   Thanks
