This patch introduces a service discovery class with a set of registered
classloaders which enables
extensions to be added to Tuscany without requiring the SPI classloader to have
visibility of the extension
classes. By default, Tuscany will continue to run in a single-classloader mode.
A multi-classloader
test has been added which runs Tuscany runtime with four classloaders forming
the hierarchy:
3rd party <-- SCA-API <-- Tuscany SPI + runtime <-- Tuscany extensions
where <-- denotes a parent<--child relation.
This patch does not address classloading requirements specific to the Node API.
