feature_flags_SUITE: New testcase to test concurrent registry loading
As of this commit, it show two issues with the current implementation of
the feature flags registry reloading:
* There is a small time window where there is no registry module loaded
while it is replaced.
* The newer registry might be initialized with older data.
Follow-up commits will address them.
