refactor: move vendor NOS Docker support into VendorDockerVM subclass
Extract the docker_exec console and GNS3_* prototype knobs (SKIP_INIT,
INTERFACE_NAMES, CONSOLE_CMD) from DockerVM into a VendorDockerVM subclass.
DockerVM is restored to its 3.1 baseline plus four small extension hooks
(_prepare_init_and_interface_env, _start_console_server,
_get_container_ifname, _cleanup_console_resources) that are pure
refactorings with zero behaviour change for existing nodes.

VendorDockerVM additionally replicates init.sh's volume persistence
(bind-mount /gns3volumes over the in-container path) via docker exec for
containers that skip init.sh, so vendor NOS config (e.g. /etc/opt/srlinux)
survives node stop/start.

The Docker manager selects VendorDockerVM when console_type == docker_exec;
all other nodes keep using DockerVM unchanged.
