Mount persistent drive to Bundle for state keeping

[Lybecker]

Is your feature request related to a problem? Please describe

An enhancement to make the Resource Processor IoC tool agnostic and allowing the Workspace Bundle to keep its own state.

Currently the Bundle when executed is passed an Azure Storage Account as a parameter TERRAFORM_STATE_CONTAINER_NAME, tfstate_storage_account_name and tfstate_resource_group_name, which as the name states is intended for the Bundle to keep the Terraform backend state.
This solution is Terraform specific and is not agnostic for other IoC solutions.

Describe the solution you'd like

For every execution, the Resource Processor should mount an Azure Storage Account container. It should be the same container for the same Bundle + Workspace. This will allow the Bundle to keep state of any kind and we can remove the Terraform specific paramenter.

As we are running on a VMSS and can run output commands on the same machine that does the deployment not sure this is needed. The IaC tooling will need to managed it's own state - but we can make MGMT_RESOURCE_GROUP_NAME and MGMT_STORAGE_ACCOUNT_NAME variables available as environment variables to be used as required.
