Create and IAMS user

Create an AWS IAM user, attach a policy to the user, and generate access keys.
 
In this section, you will create an AWS IAM user and attach the policy you just created to the user. 
You will then generate the access keys for the user. Those access keys will be used to make
 programmatic calls to AWS services via AWS CLI or APIs. If you are familiar with AWS IAM users,
 you may want to attempt to complete this section before reading the step-by-step instructions.
 
AWS IAM user name: edXProjectUser
Access type: Programmatic access and AWS Management Console access
Policy: edXProjectPolicy
Important: Download the .csv file with the access keys after creating the user. Also, make sure to click 
the Send email link to get the email instructions for signing in to the AWS Management Console as edXProjectUser.
 
Reminder! Be sure to protect your AWS account access keys like you would your credit card numbers 
or any other sensitive secret.
 
At the end of this exercise, you will not be using the access keys again. It is a security best practice
to remove IAM user credentials that are not needed. After this exercise, make sure to remove the access 
keys only (not the AWS Console password) for the IAM user - edXProjectUser. See more IAM Best Practices.
