 - Update deploy function to change into the autoscaler directory instead of metricsforwarder
 - Replace `make cf-push` with `make mta-deploy` for deploying autoscaler apps
 - Mark `mta-deploy` as .PHONY in Makefile, replacing `cf-push`

 • Extract YAML file decoding into DecodeYamlFile function for cleaner LoadConfig.
 • Implement readDbFromVCAP and readConfigFromVCAP to load database and other configurations from VCAP_SERVICES.
 • Update loadVCAPEnvs to use the new VCAP reading functions.
 • Modify tests to handle new environment variable-based configuration loading and add checks for VCAP_SERVICES parsing.
 • Fix error handling in readDbFromVCAP to return an error when multiple DB services are tagged as relational.
