* test: Add benchmark for static rbac roles
* static roles should only be allocated once
* A unit test that modifies the ast value should not mess with the globals
* Cache subject AST values to avoid reallocating slices
* chore: Optimize rego policy evaluation allocations
Manually convert to ast.Value instead of using generic
json.Marshal conversion.
* Add a unit test that prevents regressions of rego input
The optimized input is always compared to the normal json
marshal parser.
