Description

Currently docker image default configuration are included in `ProvisionInfo`. We should grab necessary config from `ProvisionInfo` into `ContainerInfo`, and handle all these runtime informations inside of docker runtime isolator. Return a `ContainerLaunchInfo` containing `working_dir`, `env` and merged `commandInfo`, etc.
