ENT-3000 Start pooling classpath scanning and related fixes (#4664)

Browse Source 
* Start pooling classpath scanning

Quickly patch synchronisation of attachment class loader cache.  Needs a revisit but more complicated due to DJVM.

Annotate away for DJVM

Take ClassGraph utils into their own file so we can exclude for DJVM

Clean up a little

* Daemonize the threads

* Seems to be some concurrency problems with use of ClassGraph.  Using a mutex for now to work around.
