Add "console_access" user attribute

[dav3r]

🗣 Description

This PR adds a new "console_access" attribute to the users map. If "console_access" is not "true" for a given user, then a login profile will not be created for that user and their console access will be disabled.

💭 Motivation and context

Certain users do not require console access, so this PR gives us the flexibility to do that.

🧪 Testing

I updated a tfvars file to include the new "console_access" attribute, applied the Terraform, and confirmed that the login profiles were deleted for users where "console_access" = false and not for users where "console_access" = true.
