This change adds an `args` parameter to the `docker.container` operation that passes said supplied args to the container at creation time. This allows the operation to support container images that have an entrypoint expecting to receive additional arguments, without needing to build+push a custom image that embeds said arguments.
This PR allows the `docker.container` operation to tear down and recreate the container when operation arguments change, instead of reporting `No change` and doing nothing. This is intended to reduce the possibility for human error/need for manual intervention when changing args to `docker.container` operations. Since it is not possible to extract all operation args from e.g. `docker inspect` output, this PR takes a similar approach to Docker Compose to tackle this issue - it serializes the operation args in a deterministic way, hashes the serialized bytes, and stores this as a label on the container. If the hash differs from a currently-running container, the container is recreated. Tested: Added additional tests for behavior when args are changing/static in different scenarios
