Bug Report

Description

In container_checker.py fixture config_reload_after_tests, on teardown performs config reload (with bgp check enabled) on DUTs in selected_rand_one_per_hwsku_hostname successively, this causes test failures (see below).

Issue Details

When more than 1 DUT is being reloaded, because this test brings down swss/syncd containers, the iBGP neighbors of the earlier DUTs being reloaded will not be able to come up, as the other DUTs swss containers are still down. This causes the test to fail.

Impact or Proposed Behavior

When more than 1 DUTs are successively called to config reload with BGP check, test fails because earlier DUTs are unable to establish iBGP sessions with DUTs that haven't been config reloaded.

DUTs should reload in parallel, allowing all iBGP neighbors to come up.
