Check for available disk space before updating package.json

[hanxue]

What is the current behavior?

1. Run a yarn command that modifies package.json, for example yarn remove cleave.js
2. Disk out of space before yarn operation is complete

Resulting error

-bash: cannot create temp file for here document: No space left on device
yarn remove v1.6.0
[1/2] 🗑  Removing module cleave.js...
error Could not write file "/Users/hanxue/PPP/jinrong/yarn-error.log": "ENOSPC: no space left on device, write"
error An unexpected error occurred: "ENOSPC: no space left on device, write".

What is the expected behavior?

yarn should warn the user if there is no disk space available before performing any actions that modifies the filesystem
