Prefix data structures with Lambda instead of namespacing them (#256)

motivation: consisten naming convention

changes:
* Lambda.InitializationContext -> LambdaInitializationContext
* Lambda.Runner -> LambdaRunner
* Lambda.Configuration -> LambdaConfiguration
* Lambda.RuntimeError -> LambdaRuntimeError
* adjust call sites, tests, and examples
