ISPN-4391 ISPN-4382 ISPN-4383 ISPN-4056 ISPN-4392 ISPN-4264 Lightweight Security, ClusterPrincipalMapper, CLI grant/deny

Sorry about the number of issues contained here, but they are all closely interconnected and dependent on one another.
A summary of the changes:
ISPN-4391 Fixes a bug in TransportConfigurationBuilder#read() and introduces a clustered test for authorization-enabled caches
ISPN-4382 Introduces a lightweight security checker which uses caller information (similar to what logging frameworks do). This improves performance and removes the requirement of a SecurityManager, but will fallback to it if present.
ISPN-4056 Finally enables caching of permission masks in the cluster registry to avoid repeated computation
ISPN-4383 Introduces a cluster registry-based PrincipalRoleMapper which allows for easy granting/denying of roles to principals
ISPN-4392 removes the mapper="classname" attribute from the global <authorization> element and replaces it with much nicer declarative elements such as <identity-role-mapper>, <cluster-role-mapper> while retaining the ability to use a custom mapper.
ISPN-4264 adds GRANT, DENY and ROLES statements to the CLI which allow manipulating role mappings when using the ClusterPrincipalMapper.

Look at the code in the static block at line 32. If the Reflection trick cannot be done, we fallback to a SecurityManager (which we do not actually install, but which provides a slightly less-performant way to do the same via getClassContext
