Do not use hypervisor key for direct connection

We should not use hypervisor key for direct connection. Hypervisor key
can be rotated and we should use key save from saved workspace.
Otherwise every time we have new hypervisor key we need to recreate
image-set to be able to ssh to virsh vms.

Fixes: OSP-23824
