Cloudsmith-cli

Fixed

- Version specifier set by `0.20.0` wasn't compatible with older versions of Python.

**Note:** This release pins the Cloudsmith API library to version 0.x due to
changes in the versioning of the library. If you're having issues with an older
version of the CLI that installs the latest API, please upgrade your CLI
version, or install `cloudsmith-api==0.49.94`.

Changed

- Pinned the Cloudsmith API library version to 0.x+ (excl. 1.x+ series).

Fixed

- Credentials config file not being populated with API key by `cloudsmith login`.

Fixed

- Missing README information on PyPi.

Added

- Support for (Objective-C and Swift) CocoaPod packages.

Added
