Refactor VHOST code

CSIT-1164 Create VM vhost tests for 2-node topology
CSIT-1173 Implement VM vhost KWs for 2-node topology

- Cleanup QemuUtils.py Library (PEP8, some TODOs, readability, multi queue,
ring size, qemu version detection)
- Cleanup VHOST KWs perf (Unify running QEMU on N-node topology)
- Add ability to configure Queues, Hyperthreading, automatically compute
number of CPU for VM/Testpmd and RXQ for Testpmd workload.
- Partial cleanup of configuration KWs (l2xc, l2bd) for 2-node
- Create IPv4 2-node KW

-| Configure guest VM with linux bridge using SMT connected via vhost-user
-| | [Documentation]
-| | ... | Start QEMU guest with two vhost-user interfaces and interconnecting
-| | ... | linux bridge. Qemu Guest uses 2048M.
-| | ...
-| | ... | *Arguments:*
-| | ... | - dut_node - DUT node to start guest VM on. Type: dictionary
-| | ... | - sock1 - Socket path for first Vhost-User interface. Type: string
-| | ... | - sock2 - Socket path for second Vhost-User interface. Type: string
-| | ... | - vm_name - QemuUtil instance name. Type: string
-| | ... | - skip - number of cpus which will be skipped. Type: int
-| | ... | - count - number of cpus which will be allocated for qemu. Type: int
+| | ... | _NOTE:_ This KW expects following test case variables to be set:
+| | ... | - cpu_count_int - Number of Physical CPUs allocated for DUT.
 | | ...
 | | ... | *Example:*
 | | ...
-| | ... | \| Guest VM with Linux Bridge using SMT connected via vhost-user is \
-| | ... | setup \| ${nodes['DUT1']} \| /tmp/sock1 \| /tmp/sock2 \| DUT1_VM \
