Support using installing node and yarn version matching the package.json engines property

Do you want to request a feature or report a bug?

What is the current behavior?
You have to specify the nodeVersion and yarnVersion

What is the expected behavior?
The install-node-and-yarn should support using the version specified in package.json engines for node and yarn.

That could be configured by using "engines" as value for nodeVersion and or yarnVersion.
In such case frontend-maven plugin should install the most recent version matching the version expression in engines for yarn/node

This is something that we'd love. We have a hard time keeping up with our frontend users when they bump versions, and this would really fix that problem. :)

Any plans for implementing this?

I have added support for the node part in #999. Support for npm/yarn is still on my TODO.
