Unexpected Custom Analyzer Execution

[ronaldpetty]

If you typo the namespace, CAs still run (unlike filters).

% k8sgpt analyze --custom-analysis -n defaut # typo, yet CA runs
AI Provider: AI not used; --explain not set

0: my-ca diskuse()
- Error: Disk usage is 80
Disk usage is 80

% k8sgpt analyze --custom-analysis -n default # expected to run
AI Provider: AI not used; --explain not set

0: my-ca diskuse()
- Error: Disk usage is 80
Disk usage is 80
1: ConfigMap default/kube-root-ca.crt()
- Error: ConfigMap kube-root-ca.crt is not used by any pods in the namespace

2: Pod default/brokenpod()
- Error: Back-off pulling image "nginx:i_dont_exist": ErrImagePull: Error response from daemon: failed to resolve reference "docker.io/library/nginx:i_dont_exist": docker.io/library/nginx:i_dont_exist: not found
