From: Hangbin Liu <redacted> The PSP test installs policy and route state, but relies on global cleanup to tear it down. That can leave flavor-specific state around when later tests are added to the same script. Add cleanup_end_flv_psp() and run it at the end of host_srv6_end_flv_psp_tests(). The host proxies are needed by all PSP testing. So move it to common setup() and no need to delete. The `set +e` is not added in the cleanup phase as del cmd usually doesn't fail. And even it failed, we can catch it on setup phase.
