Description (#5629)

lerna 6 introduces caching on builds
Lerna uses a computation cache to never rebuild the same code twice.
CHANGES:

• npm run build in 1.x will now cache builds if there are no code changes meaning we wont have to wait 1-2mins on running the same code to compile
• npm run build-no-cache in 1.x to run WITHOUT caching
• nx and nx.json file was added to dev deps to support lerna@6 caching

New Lerna 6 npm run build output

Lerna 6 when build is already cached output:
