Docker size reduction

[pi0neerpat]

This PR is focused on reducing the /api image size. It has been reduced from ~3GB to 1.17GB

Changes

• Using --production flag to skip dev dependencies saved a ton of space! (THIS IS A MUST)
• yarn cache clean saved a ton of space! (THIS IS A MUST)
• Added lerna, which is required to use the local /packages dependencies. This is working great now.
• yarn global add @redwoodjs/api-server @redwoodjs/internal to serve the api from bin

Discussion

If you do a multi-stage dockerfile, you can build everything, run migrations, then just grab the dist directories. At that point all you need is the api-server package. You can run the server as a bin via:
yarn rw-server [side]
-David's super optimistic suggestion

• I was not able to just grab the dist directories, due to missing deps for graphql-server at runtime. I ran out of time to continue down this rabbit hole.
• I could not use node-alpine because I am using packages like canvas (in my production app, not here) to render images in /api. This causes node-gyp and python errors. From a DevX point of view I believe recommending alpine is not the right path, or it should be heavily documented that both options be suggested.
