set canCreateInstance from PluginSearcher
Set CanCreateInstance from the pluginsearcher.
With some simple benchmarking I am observing a ~10% faster startup time (when running ./tap -h) since we are no longer loading dll's when checking if their CLI actions can be instantiated, going from an average of ~485ms to ~439ms in a simple installation.
Closes #700 (closed)
