Windows jumpbox VM passwords are occasionally invalid

[glennmusa]

Description

We use Terraform's password provider to generate credentials for the jumpbox VMs. Occasionally, that random value will not satisfy password requirements:

Original Error: Code="InvalidParameter" 

Message="The supplied password must be between 8-123 characters long and must satisfy at least 3 of password complexity requirements from the following:

1) Contains an uppercase character
2) Contains a lowercase character
3) Contains a numeric digit
4) Contains a special character
5) Control characters are not allowed

Steps to Reproduce
Steps to reproduce the behavior:

1. Deploy MLZ with bastion host jumpboxes (the default behavior)
2. Get unlucky

Expected behavior
Passwords that are generated meet Windows credential requirements

Actual behavior
Occasionally you'll get a password that does not meet those requirements
