nic_hotplug: modified param find_pci_cmd in order to get the right list

Current guest ip finding mechanism could not work if guest contains
multi nics. Use avocado api to get guest interface name and ip address.

qemu_io_blkdebug: fix qemu-io cases timeout issue

The old setting of 'idx' doesn't make sense because there are already couple of
virtio-serial-pci devices attaching to VM for virtio consoles. So hotplugging
a pci virtio-serial with the conflict device id causeing 'Duplicate ID' error.

The patch calculates the number of existed virtio console, Then assigns it to
the 'idx' to avoid the above error.

issues related to SR-IOV setup on Host. Currently we do not check if
we have VFs loaded after test_setup.PciAssignable. This commit would
introduce this check on qemu test side. There is another commit on
avocado-vt/virttest which would print ERROR message to users when VF
device are not created.

Add hotplug/unplug memory in loop test

Change the path of floppy images

First, The original relative path of floppy images are not exist. There is no
'data/images/' folders under 'shared' folder by default, It causes 'dd' command
failures.

If adding code into 'pre_command' of readonly_floppy.cfg to check/create
'shared/data/images/', Then the second issue jumps out:
Because 'process_command' function in env_process.py will perform
... "cd %s; %s" % (test.bindir, pre_command) ...
The test.bindir's value is assigned to '/usr/share/avocado-plugins-vt',
So we got 2 fl images under /usr/share/avocado-plugins-vt/shared/data/images/.
But in the final qemu command line parameters which generating by avocado,
The path of floppy image is /usr/share/avocado/data/avocado-vt/images/...

So I think that we insert 'cd /usr/share/avocado' to pre_command for ignoring
the effect of 'cd /usr/share/avocado-plugins-vt' and change the original
relative path info from 'shared/data/images/' to 'data/avocado-vt/images/' may
be a better choice.

1. vcpu_need_hotplug for max_cpu scenario can not be a fixed num,
   should be vcpu_need_hotplug = vcpu_maxcpus - vm.cpuinfo.smp
2. Rename param "id" to "cpuid", as there is same param in the object.
3. Enlarge waiting time after hotplug cpus, 60s is not enough for
   max cpu hotplug.
