privileged flag for local_docker scheduler

[clumsy]

Description

It is available for aws_batch already and some docker images require using privileged mode that defaults to false when using local_docker:

docker inspect --format='{{.HostConfig.Privileged}}' <CONTAINER_SHA-1>
false

Motivation/Background

See description

Detailed Proposal

Add a new option and pass it to Docker client for local_docker scheduler.
