TEIIDDES-1582 Komodo Shell Command's Help And Usage Issues
Changed SoaRepositories to use its ClassLoader and now it is finding the RepositoryProviders. Updated the commands help and usage.
Also need to change the ShellProvider's service file name because S-RAMP had refactored the packages in their  shell framework.
