Fix problem to fetch the compute name of client VM

When migrating to SNAPs a bug was introduced and could be seen in logs as:

Error when waiting for classification rules: 'module' object has no attribute
 'get_compute_client'

The cause is that get_compute_client is not a global function anymore but a
method inside a class. Besides, due to SNAPs, we need to fetch the compute
name in another way
