[ Enhancement ] Modify solution to operate without needing to specify AWS profile

[gwright99]

A subset of customers do not use profile to authenticate with their AWS accounts.

The existing design assumes that the profile will be used (e.g. ssh_config template file), which causes deployments to fail without direct modification of solution files by the operator.

The solution should expose a flag in .tfvars to indicate whether the AWS profile should be included or not when generating solution files. TBD how this will work if using S3 to store state and initial configuration of the aws TF provider.
