integration: Support of PVP and PVVP integration TCs

Integration TC support has been enhanced to support PVP
and PVVP scenarios. Definition of integration testcases
have been modified to use a sort of macros for repetitive
parts.
Additional improvements were introduced:
* instances of testcases are created only for testcases
selected for execution
* new TC definition options allow to define test specific
vswitch, VNF, traffic generator and test options
* tests filter applied on pattern specified by --tests
allows to define negative filter only; In that case
list of all tests is used as base for negative filter.
* traffic values defined within teststep passed to send_traffic
is merged with default values; This is essential for execution
of TCs with linux_bridge or SRIOV support. It also simplifies
integration TC definition
* typos removed
