redis.exceptions.ConnectionError: Error 99 connecting to localhost:6379. Cannot assign requested address.

nice to have not critical issue
but if run.sh and then exec are executed one after the other all cases will fail with
redis.exceptions.ConnectionError: Error 99 connecting to localhost:6379. Cannot assign requested address.

if we wait 10sec or so between the commands than it it will pass
i assume run.sh does not wait for redis service to start

i believe docker allows a health check and will be good to add one

or try the commands from https://github.com/opencomputeproject/SAI-Challenger/blob/main/docs/standalone_mode.md
./run.sh -a trident2 -t saivs
./exec.sh -t saivs pytest --testbed=saivs_standalone -v -k api/test_vlan.py

this is needed because of #99
ERROR api/test_vlan.py::TestSaiVlan::test_vlan_create - AssertionError: SyncD has not started yet...
whenever a test fails and causes syncd to go in a bad state we need to restart the containers and rerun next test.
