Print terraform state mv commands on interrupt

[pascal-hofmann]

When mapping a large number of resources mistakes can happen. Currently, if you abort terraform-state-mover all current mappings are lost. With these changes terraform-state-mover will print the terraform state mv commands for all the mappings that were already selected. The user can then choose to remove the faulty mappings and run the fixed commands himself.

Example output:

Interrupted. These moves would have been executed based on your selections:
terraform state mv 'openstack_networking_port_v2.this[0]' 'module.vm[0].openstack_networking_port_v2.this'
terraform state mv 'openstack_networking_port_v2.this[1]' 'module.vm[1].openstack_networking_port_v2.this'
terraform state mv 'openstack_compute_instance_v2.this[0]' 'module.vm[1].openstack_compute_instance_v2.this'
