flag(runtime): new flag format

[josedonizetti]

This PR refactor the old flag --install-path to its new format --runtime workdir=.... This refactor also starts to introduce the format we want the flags package to look like.

• All flags under pkg/corba/flags
• Only one config representation to flag and config file
• Test for flags, structured and unstructured config file
• Constant to avoid repetition
