v6.0.0

⚠ BREAKING CHANGES

• The Datastore.projectId property has been removed, and replaced with an asynchronous getProjectid() method. The projectId cannot be determined synchronously, so the previous approach was to use a {{projectId}} string placeholder if the projectId had not yet been acquired. This made it difficult to know exactly when the property would be defined.
• The library now supports Node.js v10+. The last version to support Node.js v8 is tagged legacy-8 on NPM.
