* Update README.md re: terraform.example.tfvars

Update README.md to match Jenkins. Change from copy `terraform.example.tfvars` to rename to avoid creating multiple input variable definition files.

* 0-bootstrap Update README.md sequence

Change sequence to run `terraform init` immediately after  `cp backend.tf.example backend.tf`.

Current sequence has `terraform output terraform_service_account` immediately after `cp backend.tf.example backend.tf` which generates  `Backend reinitialization required. Please run "terraform init".`

* 0-bootstrap -  Update README.md 

Change 'from previous step' to 'from Terraform's state' to make wording less dependent on precise order of steps

* Add mv command for copy/paste

Add mv terraform.example.tfvars terraform.tfvars for easy copy/paste

* Update README.md formatting error

Correct spacing formatting error in my last commit
