In a high availability deployment scenario, two clients may make a request on /healthcheck at the exact same time, which can lead to check_config returning False if the second requests changes the 'healthcheck' cache key before the first one has had time to fetch the value it had set.
A solution to counter this is to ensure different keys are used for each healthcheck.
* In some cases with numeric config items it appears that we can end up processing a string twice. This issue fixes it so that we only process the strings once at configparser load time with `before_get`
Separate docker build into two stagesto discard several binaries, builder, compiler and dev dependencies not needed for production usage. Run CTFd in a venv in `/opt/venv`. Reduce the image size from 648MB to 398MB.
