Extra CLI arguments are not passed to terraform binary

[arm4b]

Consider this bitops.config.yaml:

terraform:
    cli:
        backend-config:
            - bucket=mybucket

It should generate the following CLI per Terraform docs:

$ terraform init \
     -backend-config="bucket=mybucket"

Instead, nothing passed to the init according to logs:

+ echo 'Running terraform init'
Running terraform init
+ terraform init -input=false

---

Next, terraform plan/apply accepts $BITOPS_CONFIG_COMMAND which should be populated with CLI args:

terraform/deploy.sh

Line 75 in f1faff4

bash $SCRIPTS_DIR/terraform_plan.sh "$BITOPS_CONFIG_COMMAND"

However, this var is not created or implemented anywhere in the BitOps core.
