patch

Added a new "rejectFrontendNetworkRequests" configuration flag that can be set in the "jest" field in the root package.json:

{
  "jest": {
    "rejectFrontendNetworkRequests": true
  }
}

This flag causes rejection of any form of network requests that are attempted to be made in frontend or common package tests. This flag can only be set in the root package.json and can not be overridden in individual package configurations.
