@macaktom Thank you for submitting this PR. I'll add some notes to the original ticket that mentions this issue. I think this change requires a discussion.

The changes in this PR in it's current form could will issues since dependencies could be using this namespace.

Example: https://github.com/cnf-testsuite/cluster_tools/blob/main/cluster_tools.cr#L8

Here is some info to help out: I'm using a VS Code workspace with other dependency repos in the workspace. So I did a quick search. I did a quick search for where ClusterTools.install is being used and I see the following results (screenshot attached).

That search results includes the following dependencies:

• k8s_kernel_introspection - https://github.com/cnf-testsuite/cluster_tools
• k8s_netstat - https://github.com/cnf-testsuite/k8s_kernel_introspection
• cluster_tools - https://github.com/cnf-testsuite/k8s_netstat
