feat: hand the container engine connection Container Station's docker

napalm-device-types 2.6.0 opens a host's container engine through
`open_container_engine()`, and asks the driver for the binary through
`_container_engine_binary()`. Under QTS docker is not on PATH; the hook
now returns the path `open()` already discovers, so the Engine API stream
(`<path> system dial-stdio`) and the CLI reach Container Station while
callers only pass arguments (NetOrk/netork#765).

Version 0.2.0, requires napalm-device-types >= 2.6.0 and
napalm-linux >= 0.2.0.

 ## [Unreleased]

+
+### Added
+- `_container_engine_binary` returns Container Station's docker path, so the
+  container engine connection from napalm-device-types 2.6.0
+  (`open_container_engine("docker")`) reaches it although it is not on PATH.
+  Callers pass arguments only and never see the path (NetOrk/netork#765).

+- Requires napalm-device-types >= 2.6.0 and napalm-linux >= 0.2.0.
