feat(handlers): Register actions for each resource type

This registers the ActionSets for each resource when the handler
packages are initialized. This then allows other packages to retrieve
the ActionSets for a given resource from the action package.

The initial consumer of this will be the ratelimit package so that it
can programmatically enumerate all of the valid combinations of a
resource and action.

This leaves a number of TODO to refactor the handler packages to also
retrieve the action sets from the registered actions instead of using a
package variable. This is left as a TODO since there is some
inconsistencies in how these package variables are used between the
handlers. For example a number of packages use a map of subtypes to
ActionSets which is then used withing the handler implementation. Others
use a map, but don't seem to use it at all. And others just use an
ActionSet.
