Improvements and new features @aknysh (#66)

what

• Improvements and new features

why

• For terraform commands, put the additional arguments and flags at the end of the command. This allows to use, for example, -var=service_1_name=service-1-override-3 to override the variables defined in terraform and YAML config

atmos terraform deploy top-level-component1 -s tenant1/ue2/dev -var=service_1_name=service-1-override-3

• Add flags and logic to auto generate TF backend file

Writing backend config to file:
./examples/complete/components/terraform/test/test-component/backend.tf.json

Controlled by the CLI config:

    # Can also be set using `ATMOS_COMPONENTS_TERRAFORM_AUTO_GENERATE_BACKEND_FILE` ENV var, or `--auto-generate-backend-file` command-line argument
    auto_generate_backend_file: false

• Add remote_state_backend and remote_state_backend_type YAML config sections. They can be used to specify a different backend (different attributes, or even a completely different backend type) for remote state. It's useful for the privileged components where we use different attributes (e.g. role_arn or profile) during the cold-start and during the normal operations to get the remote state of the privileged components

      # Override backend for this component
      backend_type: static # s3, remote, vault, static, etc.
      backend:
        static:
          val1: 1
          val2: "2"
          val3: true
          val4: ""
          val5: null
      # Override remote state backend for this component
      remote_state_backend_type: static # s3, remote, vault, static, etc.
      remote_state_backend:
        static:
          val1: 1
          val2: "2"
          val3: true
          val4: ""
          val5: 5

The new remote_state_backend section in YAML is similar to the backend section - you can specify it in globals, stage globals, or override per component (which all gets deep-merged into the final remote state backend for the component). The two sections are separate and the attributes from them are not merged together
