Closes #1487 Closes #1427 Directory restructure in accordance with #1487. Also has temporary migration code to move the old directories into new structure. Also extracts all default directory names and utility functions into a `directory` crate to avoid repetitio. ~Since `validator_definition.yaml` stores absolute paths, users will have to manually change the keystore paths or delete the file to get the validators picked up by the vc.~. `validator_definition.yaml` is migrated as well from the default directories.
