Add support for reading `net/data/ssl/certificates` files
* After supporting netty, the certificates files are needed to start up the HTTP server. Those files must be moved to the emulator which happens through the changes in AndroidTest.xml, isolated-storage
has been disabled to allow the emulator to access the storage freely without restriction. Otherwise
I will have to change the destination of the data files which will result in divergence.
* Added the newly introduced test utility java classes including netty to the `jarjar_excludes` as they must not be jarjared because they are not part of the bootclasspath.
