Review request for atlas.
Bugs: ATLAS-987
https://issues.apache.org/jira/browse/ATLAS-987
Repository: atlas
Description
-------
Dependent libraries of Atlas hooks are loaded in a separate class loader, there
by making these libraries not visibile to components.
Here is the summary of the changes:
- current contents of atlas/hook/<component> directiries, including the hook
class implementation, are moved under
atlas/hook/<component>/atlas-<component>-plugin-impl directory
- a new component specific shim library, that includes the hook class
registered with the component, is placed in directory atlas/hook/<component>
- the hook class in the shim library loads all files in
atlas-<component>-plugin-impl directory in a classloader and forwards all the
calls on the shim class to the real implementation class
This implementation is same as the one used in Apache Ranger - more details in
RANGER-586.

Testing
-------
Verified that existing tests pass
Verified Hive hook successfully sends notification to Kafka, which in turn was
processed correctly by Atlas server
