Introduce enabled/disabled tool list in configuration file

[ardaguclu]

Fixes #156

This PR introduces enabled/disabled tool list in the configuration file.

Users will be able to add enabled and disabled tools in the configuration file. e.g.

enabled_tools = ["configuration_view", "events_list", "namespaces_list", "pods_list", "resources_list", "resources_get", "resources_create_or_update", "resources_delete"]
disabled_tools = ["pods_delete", "pods_top", "pods_log", "pods_run", "pods_exec"]

This list will be applied to the given profile (full is the default);

• If enabled list is empty, all the tools given in the profile will be populated
• If enabled list is not empty, only the enabled tools will be populated
• If disabled list is not empty, specifically disabled tools will be removed from the tool list.

This PR partially fixes #151

In a follow up PR, I'll add validations to prevent duplicate entries in both enable and disabled list.

Currently implementing your review suggestions. Will ping you there when ready for a last review

I think it would be good to move the description comment here since to clarify its purpose:

// When true, expose only tools annotated with readOnlyHint=true

Same for DisableDestructive

[ardaguclu]

Good point. I'll add these comments.

[ardaguclu]

Updated.

LGTM, however, I think I'd rename allowed_tools to enabled_tools and denied_tools to disabled_tools.

enabled/disabled is more descriptive than allowed/denied. I'll update with that.

LGTM, thx!
