What changes were proposed in this pull request?
this patch is built on top of Madhan's approach.
normalize() is correctly protected in the base patch, but ServiceDefUtil.normalizeAccessTypeDefs() — called separately right after it in RangerPolicyRepository and PolicyEngine — was still mutating the shared serviceDef's access-type lists with no synchronization. This PR moves that logic into RangerServiceDef with the same double-checked-locking pattern already used for normalize(), and updates both call sites.
How was this patch tested?
Includes a concurrency test that fails against the base patch alone, and passes once this fix is applied on top.
