Unified way to provide configurations and env variables(proposal 1)
In this proposal, everything in os.environ can be accessed directly using const, and with the exact name os.environ defined. The name of a configuration is totally decided by config_functest.yaml, which is the joint name of each level with '_'. This version requires us to naming each level in yaml in a little cleancode way, or else the configuration name would become ugly. Let me take the current defination of general.directories as instance, the configuration name will be 'directories_dir_repo_functest', looks not very good. But if we make some adaption: general: dir: repo_functest: it will become 'dir_repo_functest', looks a little better. For vIMs is well defined, let me take it for example, the configuration names will look like: vIMS_clearwater_blueprint_url vIMS_clearwater_blueprint_file_name vIMS_clearwater_blueprint_name vIMS_clearwater_blueprint_branch vIMS_clearwater_blueprint_destination_folder vIMS_clearwater_deployment-name Change-Id: I18ec8686d9cfb2b80a370d422c6ad81a8800585c Signed-off-by: SerenaFeng <feng.xiaowei@zte.com.cn>
