Upgrade dependency to Webpack 4

[ibhag]

Webpack 4 has lot of interesting features which can help improve performance of our products. Grommet-cli uses 3.x version, do you know of a way where we can keep using grommet-cli but that uses webpack 4 rather than webpack 3 or else please upgrade to webpack 4

Can we please get an ETA for this. Our organization is planning to work on performance improvements which are possible only with webpack 4 and we are blocked because of this.

we gladly accept pull requests to make the change to webpack 4.

we recently deprecated grommet-cli in favor of create react app. We are not planning to add new features here, but updating to webpack 4 is desirable but grommet-cli is lower in our list of things to tackle. We are instead relying in the community to chime in and help with that.
