upload: Reporting matched profile into vars[]

This commit is pretty simple and provided into server's answer the
matched profile like :

var = {'disk': 'vda',
 'edeploy_profile': 'kvm-test',
 'eth': 'eth0',
 'eth-io': 'eth1',
 'eth-mgmt': 'eth2',

This information could be used later when the init is failing to inform
the server that this profile failed at installing.
