GH-467 Added initial support for GET method to FunctionEndpointInitializer

Browse Source 
At the moment support is rudimentary as it does not include any type conversion, but neither does POST so it is consistent.
Given that BeanFactoryAwareFunctionRegistry provides all that functionality already perhaps the proper fix with regard to converter would be to use it or part of it in place of InMemoryFunctionCatalog currently used.

Resolves #467
