Fix SDLCLI healthcheck to ignore ghost Sentinels
Fix SDLCLI 'healthcheck' command to ignore Redis Sentinel entries what
have a zero port numbers, because these extra entries are not valid
entries but instead are caused by a bug (#9240) in Redis server. Until
there is a fix for the Redis server issue available, we ignore these
ghost Redis Sentinel entries from SDLCLI 'healthcheck' command's
validation.
