Various changes after testing the modules

[noemif]

Fixes:

• Module 1: missing assets when customising the static site
• Module 2: SharedParentStack cloudformation parameter instructions missing from 2.2.4
• Module 2: There is already an existing pipeline, need to create a new one
• General: typos/grammar fixes

Other comments (things I couldn't fix in code):

Module 1:

• There was no devops_girls keypair in account 214953911892
• The "Edit Amazon EC2 configuration" step is easily missed, and that leads to a lot of pain later on. Need to highlight that step.

Module 2:

• Snapshot 3-2-2-6 missing the SharedParentStack cloudformation parameter
• Also, snapshot 3-2-2-6 shows an IAM role (not mentioned in the instructions)
• Section 2.2.18 and snapshot 3-2-2-13 say that simple-app should display a "DevOps Girls" webpage, but I only got the default Apache "It Works" page.
• The CodeBuild project VPC settings are unclear, my build kept failing and I'm not sure if it's related
• I think the path for index.html in Dockerfile should be ./webpage/index.html, not ./index.html, but I couldn't get the build to work to test this.

General feedback on the course structure:

• It's quite ambitious ! Unlike the previous bootcamp, at no point do attendees get to deploy a simple app manually on an EC2 instance, in the console, to get a feel for what is actually happening behind the scenes. We need to monitor attendees carefully to see if this is the way to introduce CD/CI to a crowd of potentially non-coders.

• That said, thumbs up for using CodeStar/CodeCommit/CodePipeline as an AWS-integrated way of doing CD/CI, which we DO need to show.

I'll do my best to test module 3 before COB today...

Cheers,
Noemi

Hiya ! not sure who's monitoring this repo, so I'm just going to rudely ping all existing contributors:

@ramps41 @shivaman @verofa

Also I think some of my comments fixes have already been integrated this morning, sorry for the redundancy !

Looking forward to seeing you all on Saturday,
Noemi

Added a few more fixes after running module 3.

Mainly minor typos and grammar things, that module was a lot smoother than ECS :-)

Other more significant changes:

• S3 upload step: explain where to get the files from (I don't think we clone the bootcamp repo earlier)
• S3 upload step: cater for ppl without the AWS CLI (do we cover installation at any point ?)
• Deployment: add instruction to reduce timout

ping @shivaman :-)
