DynamicMapLayer and ImageMapLayer with json/image + token/proxy support

[jwasilgeo]

As of v2.3.3, DynamicMapLayer.js and ImageMapLayer.js (both of which extend from RasterLayer) do not fully support certain options combinations of f: 'json' or f: 'image' coupled with a token or a proxy.

DynamicMapLayer

token support

• f: 'json' and token in source code
• f: 'json' and token has unit test
• f: 'image' and token in source code
• f: 'image' and token has unit test

proxy support

• f: 'json' and proxy in source code
• f: 'json' and proxy has unit test
• f: 'image' and proxy in source code
  • (would need to remove the entire f override in the initialize method)
• f: 'image' and proxy has unit test

ImageMapLayer

token support

• f: 'json' and token in source code
• f: 'json' and token has unit test
• f: 'image' and token in source code
• f: 'image' and token has unit test

proxy support

• f: 'json' and proxy in source code
• f: 'json' and proxy has unit test
• f: 'image' and proxy in source code
• f: 'image' and proxy has unit test

@jwasilgeo I think we're good now after all those PRs. Could you please take a look and close if you think it's resolved.

I've taken another look and I agree. Thanks for all that--huge help!
