karmor uninstall should remove annotations/policies by default

[DelusionalOptimist]

Description

Currently when users remove KubeArmor with karmor uninstall, by default there pods are left with AppArmor annotations.
This is not desired as it may cause issues in certain cases like:

• AppArmor policies were deleted manually
• Enforcer was changed to BPF LSM and apparmor was disabled
  etc.

They have to use --force flag for the same which is also not documented anywhere.

Improvement

Remove annotations and policies/CR(D)s by default.
If user wants to keep it, they use the --keep-policies flag. (Could use suggestions on the flag name)
