Description

Provide a means to invoke static factory methods for flux components. E.g:

Java signature:

public static MyComponent newInstance(String... params)

Yaml:

    className: "org.apache.storm.flux.test.MyComponent"
    factory: "newInstance"
    factoryArgs: ["a", "b", "c"]

Also include a fix for non-primitive numbers, so constructs like the following work:

Java constructor:

public TestBolt(Long l){}

Yaml:

  - id: "bolt-4"
    className: "org.apache.storm.flux.test.TestBolt"
    constructorArgs:
      - 10
    parallelism: 1

(Before fix the above would fail because snakeyaml would convert `10` to an Integer.)
