Increase payload limit

[juliaelman]

Recently we merged in a rather large pull request for the pattern library project and was rejected b/c of the size: uswds/uswds#54

[mbland]

So here's the stack trace:

Error: request entity too large

I found this in hookshot/node_modules/body-parser/lib/types/json.js:

/**                                                                             
 * Create a middleware to parse JSON bodies.                                    
 *                                                                              
 * @param {object} [options]                                                    
 * @return {function}                                                           
 * @api public                                                                  
 */                                                                             

function json(options) {                                                        
  options = options || {}                                                       

  var limit = typeof options.limit !== 'number'                                 
    ? bytes(options.limit || '100kb')                                           
    : options.limit

And wouldn't you know it, it's hardcoded in hookshot/lib/index.js:

var bodyParser = require('body-parser');                                        
var normalize = require('path').normalize;                                      
var spawn = require('child_process').spawn;
var express = require('express');                                               

module.exports = function (ref, action) {

  // create express instance
  var hookshot = express();

  // middleware
  hookshot.use(bodyParser.urlencoded({ extended: false }));                     
  hookshot.use(bodyParser.json());

Lemme think for a minute how to get around this. I mean, who would ever need to parse a >100KB webhook payload? :-P

So the running server is fixed, but I'll keep this open until coreh/hookshot#12 and #15 are committed and the updated version of hookshot running on https://pages.18f.gov is installed from npm rather than from 18F/hookshot.

Is this issue fixed or a workaround is available. I see last update was an year ago. I am unable to recollect how it can be resolved though we are waiting to committ.

@divyatechryde I'm not sure coreh/hookshot#12 was committed.
