CORDA-2345: Simplified TestCordapp to make it inline with the recent CorDapp versioning changes (#4434)

Browse Source 
TestCordapp has now two implementations to clearly separate the two use cases it has in the Corda repo:

* TestCordappImpl which implements the revised public API of TestCordapp; namely that a TestCordapp instance references a real CorDapp jar on the classpath. This is either an external dependency jar in which case it’s taken as is and given to the node, or it’s a local gradle project in which case it’s compiled using the gradle “jar” task to generate the CorDapp jar. This approach means the jar has all the original CorDapp versioning information, which is important that it’s correct when testing. To this end, TestCordapp only needs to expose the ability to specify the app’s config. All the remaining properties have moved to CustomCordapp.

* CustomCordapp for creating arbitrary custom CorDapps, including specifying the jar’s MANIFEST values. This is internal API and only used for testing the platform. Technically this shouldn’t implement TestCordapp but does so to reduce the complexity of the driver and mock network.
