test: add Node.js 10 to the CI test matrix (#314)

Until nodejs/node#20516 have been resolved,
we have disabled the hapi tests to make sure we still test as much as
possible on Node.js 10

 Some versions of Node.js contain bugs or issues that limit our ability to instrument them correctly.
 The following versions of Node.js are known to not be fully instrumented:
 
-- v8.0.x - Recommended solution: Upgrade to v8.2.0 or higher to get full support
+- v10.x - Async/Await in Node.js 10 is currently buggy and can therefore not be supported (https://github.com/nodejs/node/issues/20516:[nodejs/node#20516])
 - v8.1.x - Recommended solution: Upgrade to v8.2.0 or higher to get full support
+- v8.0.x - Recommended solution: Upgrade to v8.2.0 or higher to get full support
 
 NOTE: Support for Node.js 8.2.0 and above is experimental as it makes use of the experimental core API https://nodejs.org/api/async_hooks.html[Async Hooks].
 If you experience any issues related to using Async Hooks,
