Agent Framework

[troyronda]

• Should be a framework package that glues together the chosen handlers, resolvers, stores, etc.
• Protocols need to be implementable both inside the main Aries repo and outside by downstream repos. i.e., use decoupled patterns.
• Should include a defaults Option that provides the (curated) default list of handlers, resolvers, stores, etc. to make a default instantiation of the framework easy.
• Used by agent implementations (including reference agents).

The reference agent (#68) consumes this framework.
