Add two shell libaries with utilities to write shell scripts. The 'utils/shlog' file provides macro names for ANSI escape sequences to control color output on terminals, a 'log' functions with pre-defined behavior for ERROR, WARN, DEBUG, INFO and SUCCESS level messages, and the 'quiet' function which executes a command and hides its output. The 'utils/shfun' file provides an interruptinon handler for SIGINT, and the following functions: - run_if_exists: run a command if it is available - cleanup: cleanup environment, possibly stopping a container and a Python virtual environment. - start_virtual_environmnt: initiates a Python virtual environment - in_python_virtualenv: test if the script is running inside a Python virtual environment - die: abort the script with an error message end exit code 1 New files: - utils/shlog - utils/shfun
