Replace the manual loop for checking excluded namespaces with
the built-in slices.Contains function. This change enhances
the readability and efficiency of the code, while also
allowing for wildcard matching in exclusion.
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.
