#1966, #1967

Short description and why it's useful

• Replace he.js with https://github.com/adnaan1703/lean-he (tree shaked version to only use decode)
• Replace object-hash with https://github.com/emn178/js-sha3 (smaller, plus MD5 and SHA1 algorithms are obsolete)
• Move webpack-bundle-analyzer to webpack.client to avoid launching multiple version of the server
• Refactor lodash imports to enable lodash-es tree shaking
• Bump dependencies

Screenshots of visual changes before/after (if there are any)

Screenshot of passed e2e tests (if you are using our standard setup as a backend)

(run yarn test:e2e and paste the results. If you are not using our standard backend setup or demo.vuestorefront.io you can ommit this step)

Upgrade Notes and Changelog

• No upgrade steps required (100% backward compatibility)
• I've updated the Upgrade notes and Changelog on how to port existing VS sites with this new feature

Contribution and currently important rules acceptance

• I read and followed contribution rules
• I read the TypeScript Action Plan and adjusted my PR according to it
• I read about Vue Storefront Modules and I am aware that every new feature should be a module
