Fixed Build/Runtime errors + Dockerized

[cardboardcode]

Purpose of Pull Request

This pull request targets the following faulty python code statements causing build/runtime errors when attempting to build door_adapter_template ROS 2 package.

Fixed bug 🐛

Build Error: faulty string literal - Bug 1
Runtime Error: faulty import of DoorClientAPI class - Bug 2
Build Error: Missing maintainer email - Bug 3

Fix applied 🐛 🤛

• Corrected the python statements mentioned above. Verified it via a successful build via ROS 2 colcon build as well as observed no further runtime error when running.
• Standardised door_adapter_template throughout door_adapter_template ROS 2 package, replacing instances of door_adapter

New feature implementation ➕

Dockerised door_adapter_template to ensure ease-of-setup for future developers as well as provided up-to-date instructions on how to use it properly.

Implemented features

• Added root Dockerfile based on ROS 2 Humble.
• Added Docker Build and Docker Run instructions in root README.md

Implementation description

Please run the commands below to verify that door_adapter_template faces no build errors when compiling with colcon build and no runtime errors when running:

cd $HOME

git clone https://github.com/KABAM-Robotics/door_adapter_template --branch bugfix/fix_package_compilation_error --depth 1 --single-branch

cd door_adapter_template

docker build -t door_adapter_template:humble .

The docker image door_adapter_template:humble should build with no errors.

cd $HOME/door_adapter_template

docker run -it --rm \
    --name door_adapter_template_c \
    --network host \
    -v /dev/shm:/dev/shm \
    -v ./door_adapter_template/config.yaml:/door_adapter_template_ws/src/door_adapter_template/config.yaml \
door_adapter_template:humble /bin/bash -c \
"source /ros_entrypoint.sh && ros2 run door_adapter_template door_adapter --config_file /door_adapter_template_ws/src/door_adapter_template/config.yaml"
