[BUG] The default values can't be changed in cluster config file for virtual machine.

Describe the bug It is not possible to change default values in configuration section for infrastructure/virtual-machine such as:

• disk_size_gb
• offer
• sku etc… in cluster config file. Terraform use always default ones.

How to reproduce Steps to reproduce the behavior:

1. execute epicli init ... (with params)
2. edit config file and change default os_disk_size or os image
3. execute epicli apply ...

Expected behavior I would like to create cluster with the values which I set in my configuration file. If I set 64GB os disk size, I would like to have 64GB os disk size, not the default 32GB

@rpudlowski93 For now, the only option to change these parameters is to provide the configuration for each vm like this:

✔️ Fixed. Now we can easily change the default values for OS image, vm size, disk size, etc.
