----------------------------------------------
So I tried to fix this by using global and local factory, but when I want to
see if it works by letting it print logs from filterConfigMaps. It just can't
seem to let it print out the logs I want somehow.
> Watch configmap only in yunikorn's deployed namespace

> Currently, Yunikorn uses configmap informer to handle configuration hot
> reload.
> However, In current implementation informer watches all namespaces even only
> need to watch namespace in which yunikorn is deployed. It causes in efficient
> behavior when sync and cache configmap states. If there is too many unrelated
> configmap in other namespace cause long recovery time to list and memory
> presure to handle configmap caches which is redundant.
> So, If we could replace configmap informer to namespace restricted one, it
> would improve startup / recovery time and reduce memory usage
