Removing phy2phy_tput_mod_vlan test case execution from daily job
This patch is used to remove phy2phy_tput_mod_vlan packet forwarding test case execution from kvmfornfv daily job as this test case has no guest involved. Kvmfornfv will execute only test cases that involves atleast one or more guests. Note: phy2phy_tput test case is an exception and will be used in future for comparing results and debugging if needed.
