v2.5.0

This release changes the packages names from zos to @openzeppelin/cli, and zos-lib to @openzeppelin/upgrades, following the company-wide rebranding. It also introduces the following changes, while retaining support for the older variations.

• The zos command is now openzeppelin or oz, though zos is still supported
• The proxy contracts use storage slots as per EIP1967, though the old slots are still supported
• The project configuration files are now stored under an .openzeppelin folder, instead of at the root of the project, though the old config file locations are still supported
• The zosversion configuration key was renamed to manifestVersion, though zosversion is still supported

All in all, you can upgrade by just installing the new packages, without needing to migrate your files at all. Run npm install @openzeppelin/cli and let us know what you think!
