[V3] test_plans/dcf_lifecycle_test_plan: add test plan for CVL DCF enable device reset API

DCF PMD need to support rte_eth_dev_reset.The reason is that when a DCF instance be killed, all the flow rules still exist in hardware. when DCF gets to reconnect,
It has already lost the flow context, and if the application wants to create new rules, they may fail because FW reports that the rules already exist.The current
workaround assumes that the user can turn off / turn on VF trust mode, so kernel PF will reset DCF by removing all old rules.The rte_eth_dev_reset API provides
a more elegant way for the application to reset DCF through the commmad "port reset all" when reconnecting.

Above Prerequisites is common, not special for reset cases, suggest putting on top of the test plan if need.

This test case is testing resetting dcf port by "echo" cmd. 
Will you also kill the DCF testpmd for this case? if not, kill sample should not common step.
