More work on USERGRID-1868 and USERGRID-1874 in the services module to:

 o Add Maven profiles
 o Convert the code based to use some of the new constructs
Isolating the TokenServiceIT because it seems to have issues running
together with the other tests. This suggest there still are some
shared structures that are interfering with one another.
Removing the now useless ShiroHelperRunner and bumping up the
heap after a crash in the core module.
