In PRs: sonic-net/sonic-mgmt#15643 and sonic-net/sonic-mgmt#15881 We implemented multi-servers testbed design, however, to enable parsing multi-servers testbed definition, raise this PR to fix out of key error. The code is already in master branch, and we only need the four lines code to be backport to 202411 and 202405
