DeatByJava - Containerized Java Load Generator

Basic Java-based load generator. The container runs a fixed number of expensive operations based on the request parameter [n]. The expensive operations will peg a core for however long it takes to complete the operations, so that when contention occurs, the “however long” takes longer. The expensive operation is based on Math functions.
