   initialization::create_directories()
     Creates folders to mount inside the container. 
   initialization::check_docker_version()
    
   This checks the docker version and instructs if failed to install docker. Check if the docker available is good to go
   
   build_images::forget_last_answer()
   To remove the forced answer given previously. 
   
   build_images::determine_docker_cache_strategy()
   We use pulled docker image cache by default for CI images 
   
   build_images::rebuild_ci_image_if_needed()
   Checks if rebuild CI image is needed or not. Checks if docker build is needed. If yes, confirms image rebuild.
   
   breeze::print_badge()
   
   This emits the airflow logo, backend(mysql, postgres etc), backend_version, checks the cache to see if we have to suppress the asciiart logo. If not, print the visual art for airflow
   
   initialization::summarize_build_environment()
   
   How do we get values for all env variables initialized here? Are all of them are constants or do we have to compute on-demand or pass as a param? I will have to verify this part.
   
   breeze::print_setup_instructions()
   Prints setup instruction in case we find that autocomplete is not set
   
   
   resoure_check() in run_resource_check.py
   
   breeze::prepare_command_file()
   	This generates script inside build_cache dir depending on the type of configuration chosen and env var for breeze and file that can be run to use the docker command.
   	
   @potiuk I tried to find the logical steps getting executed in entering the shell. Please correct me if any of my understanding is wrong.
