unable to run docker daemon with azure container instance (created using az container create)

**Is your feature request related to a problem? Please describe.**
As a developer, I would like to create ACI to run build pipeline, which need to install docker and other CLI with dockerfile.

However, in order to run docker daemon, docker argument for volume needs to be passed in.

**Describe the solution you'd like**
Please allow docker run arg (-v) to be passed in.

**Describe alternatives you've considered**
Our build agent is heavily customized, we'd like to utilize ACI and pre-built docker image to save time provisioning a machine. We can create custom VM and run as Azure Pipeline build agent, but that's too expensive.

**Additional context**
