Fix hapi.js issue with BadRequest when parsing invalid cookie value

problem.md

Problem

• multple apps sharing the same cookie domain
• one app (express.js) is using a secure cookie express:sess and express:sess.sig
• the hapi.js app tries to parse these cookies and fails returning 400 BadRequest error to client

I don't want hapi to return an error response to the client just because it gets a cookie it cant parse and doesn't care about. I tried setting

server.config({
  state: {
    cookie: {
       failaction: "log"
    }
  }
  // other config omitted
});

but cookie or { state: { failAction: ... }} was not allowed and prevented the server from starting.

Solution

 server.connection({
  host: "0.0.0.0",
  port: 8081,
  routes: {
    cors: true
  },
  state: {
    ignoreErrors: true //  <== this works
  }
});

It's not entirely clear form the docs what to do but peeking at the source for statehood shows it is expecting an object that has property ignoreErrors -- nthing at all like what the hapi docs say.
