aws inventory script not working for customer using 2FA access #110
Description
customer uses MFA for all their AWS account access. They have local set up that sets environment variables (list below) for terminal sessions. Running the inventory script like ./lw_aws_inventory.sh -o OrganizationAccountAccessRole -p lsnetsinger -r us-east-1 threw error for getCallerIdentity API call. Also confirmed script worked fine once MFA turned off.
Request to improve the script so these variables should take precedence for access AWS account if present in the environment.
