feat: improve LimitRange management in namespaces

Browse Source 
Add logging for LimitRange checks, enhance error handling for 
listing LimitRanges, and streamline the creation and deletion 
of the 'extreme-request-defaults' LimitRange based on namespace 
exclusion. This improves reliability and visibility during 
namespace management.
