Check interaction of field masking with audit logging

The test ComplianceAuditLogTest.testReadWriteDfm fails ATM:

java.lang.AssertionError: Messages arrived: {
  "audit_cluster_name" : "utest_n1_fnull_t15609296706395",

  ],
  "audit_trace_resolved_indices" : [

  ],
  "audit_node_host_name" : "127.0.0.1"
}

This is likely because the new field masking impl does not properly interact with audit logging in order to remove masked fields.

This is supposed to look like this:

{
  "audit_cluster_name" : "utest_n1_fnull_t15949756818180",
  "audit_node_name" : "node_utest_n1_fnull_t15949756818180_num1",
  "audit_category" : "COMPLIANCE_DOC_READ",
  "audit_request_origin" : "REST",

  "audit_request_effective_user" : "fls_audit",

}
