support custom properties for corb2

[joemfb]

It'd be nice if we could pass custom properties to corb: https://stackoverflow.com/questions/31751243/marklogic-8-corb-pass-arguments-other-than-uri

Also, we should probably be bundling/supporting corb2, if we're not already ...

If I read and remember correctly, corb doesn't support such properties, so this means we would have to implement support for corb2 then. Makes sense..

@hansenmc with your pull request, this issue can be closed, right?

Definitely if the custom properties are set in an options file, but I think I may need to make a slight adjustment to ensure that if passed in via commandline, a lower or camelCased property does not get turned into UPPER-CASE (e.g. URIS-MODULE.foo => URIS-MODULE.FOO). We want to ensure the base option is upper-case, but preserve case for the custom property. I can get that added this evening.

Above mentioned fix was added and merged, and latest corb jar with usage included as well!
