title: Custom Scope in Micronaut
body: <p>Micronauters, </p>
  
  <p>I'm trying to implement a custom scope for my micronaut application to handle multi-tenancy.  I would like to inject tenancy information into a context and be able to reference that context within a method using something like a MethodInterceptor.  There isn't much documentation in the form of examples out there on how I would do this.  Has anyone come across this use case?  It would seem to be pretty common among multi-tenant applications.  Thanks!</p>
