LU-16524 sec: enforce rbac roles

There are 5 different rbac roles defined via nodemap:
- byfid_ops, to allow operations by FID (e.g. 'lfs rmfid').
- chlg_ops, to allow access to Lustre Changelogs.
- dne_ops, to allow operations related to DNE (e.g. 'lfs mkdir').
- file_perms, to allow modifications of file permissions and owners.
- quota_ops, to allow quota modifications.
Enforce these roles by checking the value of the 'rbac' nodemap
property on server side and returning -EPERM if operation is
forbidden.

Add sanity-sec test_64* to exercise these capabilities.
