Inversion of control / dependency injection for python

TODO:

• Add AbstractLifetime class for singleton and scoped lifetimes
• Use ServiceRequest as the key to retrieve a service instead of just a type
  • This would change AbstractServiceProvider, AbstractServiceContainer, ServiceFactory to accept a ServiceRequest object that defines what service needs to be returned. It still allows for retrieving based on a type, but also allows for more complex resolving needs.
  • Maybe add a Resolver layer inside the ServiceProvider that takes the request and ChainMap of service factories to resolve the requested service. It could be customized by user if needed.
