Performance improvements

[sapessi]

• Framework version: 1.0.1

• Implementations: Jersey / Spring / Spring Boot / Spark

• Add initialize() method and move framework initialization to it. By default the initialize method should be called by the static getAwsProxyHandler()

• Move initialization of ObjectReader and ObjectWriter to the constructor of LambdaContainerHandler

Both of these are addressed

@sapessi Thanks for bringing in the performance improvements by 1.1. release. Is there a benchmark testing to show mow much it reduce the cold start time, to what degree ?
