Part of https://issues.redhat.com/browse/RHCLOUD-32282

We will use the quickstarts client as an initial example of how to update the remaining clients to the new builder.

Upgrading to the new builder will result in breaking changes - the build folder will no longer contain a `dist` sub-directory; it will include the common JS build in the root and a folder for the `esm` build. We will need to publish these changes as a major semver (x.x.x) bump in npm.
