Yarn: Perform retry for 50x errors

[ishitatsuyuki]

Things like S3 has a possibility to return 50x errors temporarily.

https://registry.yarnpkg.com/@theia/file-search/-/file-search-0.4.0-next.bace685a.tgz: Request failed \"503 Service Unavailable\"

We should implement retry on 50x just as what we do for network errors, preferably with exponential backoff.

I think I was running yarn 1.x at that time and it seems that the patch wasn't working as intended.

This definitely still a problem, i'm getting annoying failures on CI builds...

An unexpected error occurred: "https://registry.yarnpkg.com/@storybook/addon-actions/-/addon-actions-4.1.9.tgz: Request failed \"500 Internal Server Error\""

An unexpected error occurred: "https://registry.yarnpkg.com/@atlaskit/theme/-/theme-7.0.4.tgz: Request failed \"500 Internal Server Error\"".

and a couple more within the last few hours.

(Yarn 1.13.0)

npm registry is having issues again today. It'd be great if yarn would implement retry behavior for 5xx errors.

$ yarn install
yarn install v1.19.0
