Add support for terraform workspace

[eistrati]

Reference: https://www.terraform.io/docs/state/workspaces.html

Config example:

your_tf_script_name:
  root: './your_tf_script_path'
  terraform:
    plan: true
    apply: false
    destroy: false
    var-files:
      - prod.tfvars
      - common.tfvars
    vars:
      region: 'us-west-2'
    current-workspace: default
    available-workspaces:
      dev:
        plan: true
        apply: true
        destroy: true
        var-files:
          - dev.tfvars
          - common.tfvars
      test:
        plan: true
        apply: true
        destroy: true
        var-files:
          - test.tfvars
          - common.tfvars
      stage:
        plan: true
        apply: true
        destroy: false
        var-files:
          - stage.tfvars
          - common.tfvars

CLI example:

recink run terraform -vv \
  --include-modules="your_tf_script_name"\
  --tf-workspace="dev"\
  --tf-version="0.11.0"\
  --tf-varfiles="dev.tfvars,common.tfvars"\
  --tf-vars="region:\"${region}\"\
,account_name:${account_name}\
,account_id:${account_id}\
,vpc_id:${vpc_id}\
,vpc_cidr:${vpc_cidr}"

Clarification:

1. --tf-workspace="dev" <==> --custom-config="your_tf_script_name.terraform.current-workspace:dev"
2. --tf-version="0.11.0" <==> --custom-config="$.terraform.version:0.11.0"
3. --include-modules or --exclude-modules && --tf-version="0.11.0" <==> --custom-config="module1.terraform.version:0.11.0,module2.terraform.version:0.11.0,..."
4. --tf-varfiles="v0,v1,..." <==> --custom-config="$.terraform.var-files.0:v0,$.terraform.var-files.1:v1,..."
5. --include-modules or --exclude-modules && --tf-varfiles="v0,v1,..." <==> --custom-config="module1.terraform.var-files.0:v0,module1.terraform.var-files.1:v1,...,module2.terraform.var-files.0:v0,module2.terraform.var-files.1:v1,..."

Intresting task, but workspace work only in version > 0.11.0 (tested), declared minimal version is 0.10, but in this version TF have some bugs. Before working with the "workspace", we will check the version.
