Implement entitlement security.unconfined #950
Description
I would like to run privileged commands in my builds. I saw the --allow security.unconfined flag, but seeing the following when using it:
2019/04/19 05:28:51 http2: server connection error from localhost: connection error: PROTOCOL_ERROR
error: failed to solve: rpc error: code = Unknown desc = entitlement security.unconfined is not allowed
Makefile:158: recipe for target 'test' failed
