This commit adds three new commands for managing plugins. The `list` command will show which plugins are currently registered and their enabled state. The `enable` and `disable` commands can be used to enable or disable plugins. A disabled plugin will not show up to the PluginManager when it iterates over available plugins of a particular type. The purpose of these commands is to provide more visibility into registered plugins and allow users to disable plugins for experimental perf reasons. There are a few limitations to the current implementation 1. Only SystemRuntime and InstrumentationRuntime plugins are currently supported. We can easily extend the existing implementation to support more types. The scope was limited to these plugins to keep the PR size manageable. 2. Only "statically" know plugin types are supported (i.e. those managed by the PluginManager and not from `plugin load`). It is possibly we could support dynamic plugins as well, but I have not looked into it yet.

# This test validates the plugin enable and disable commands.

# Currently it works only for system-runtime plugins and we only have one

# system runtime plugin so testing is a bit limited.
