Remove com.atlassian.crowd.event.listener.ResetPasswordListener

ResetPasswordListener responds to certain types of password reset events by sending notification email, but fills in its template with the wrong properties. It's called indirectly by DirectoryManagerGeneric.resetPassword, which is deprecated.

The resulting email doesn't include the new password or a reset link so its only use is to notify.

We should note that this method will no longer cause email to be sent and remove the listener.
