Unpinned a127 dependencies now bringing in packages using ES6 features that don't work with version of Node (v0.10.32) used by Apigee

[LittleColin]

The packages.json has:

"nodemon": "^1.9.1" 

This is now bringing in v1.12.5 that contains an arrow function so I get the following error when trying to run locally:

/home/ubuntu/.nvm/v0.10.32/lib/node_modules/apigee-127/node_modules/nodemon/lib/config/exec.js:161
    .map(ext => ext.replace(/^\./, ''))

Pinning this to 1.9.1 then reveals an issue with super-agent version which is an unpinned dependency of swagger-tools that is now using const.
