Parsoid/Upgrade packages

We're aiming for deterministic package installs and using the tools the package manager, npm, provides. Please install npm v3.x or v4.x (not v1.x or 2.x or 5.x or 6.x). For a consistent package state, try starting with:

npm i -g npm@4
/bin/rm -rf node_modules
npm install

Upgrading a package (or adding a new one) should go as follows:

npm --version
# should give you v3.10.10 or above (does not work with v1 or v2, and there's a bug in v3.10.8-9)
npm i --no-optional package@major.minor.patch --save(-dev)
npm shrinkwrap --dev
# git review

Now everyone's happy and the patch got merged. Go to the deploy repo and:

git pull origin master
git submodule update --init
cd src/
git checkout sha-of-the-above-commit
cd ..
rm -rf node_modules/
npm i --no-optional
git status
# verify only what's expected got changed
git review

Note that all the --no-optional business here is because service-runner > bunyan > dtrace-provider is an optional binary dependency that we want to avoid putting in the deploy repo.

If you're interested, at this point you can run npm i -g removeNPMAbsolutePaths and then removeNPMAbsolutePaths . to remove unnecessary local information like the install path.
