BREAKING CHANGES

As previously announced, google-cloud-cpp now requires C++ >= 17. This is motivated by similar changes in our dependencies, and because C++ 17 has been the default C++ version in all the compilers we support for several years.

We think this change is large enough that deserves a major version bump to signal the new requirements. Additionally, we have decommissioned previously deprecated API features and have also made some previously optional dependencies required.
