Byte Buddy 0.7-rc6

• Refactored AgentBuilder.Default to delegate exceptions during redefinitions to listener instead of throwing them.
• Fixed bug where instrumented type would count to auxiliary types and trigger injection strategy.
• Fixed bug where interface types would resolve to a non-generic type signature.
• Added strategy to use redefinition or retransformation of the Instrumentation API when building agents.
• Added lazy facade to be used by agent builder to improve performance for name-based matchers.
