[Feature Request]: Specifying multiple hosts for single cluster entry

Problem description (Describe the problem you would like to solve with this feature request or suggested idea).

When having redis cluster I'd like to still be able to connect to the cluster from Redis Insighteven if one of the nodes is down. Currently if the host which is specified is down then whole cluster is not reachable from Redis Insight.

How often do you encounter this problem (Describe how frequently this problem occurs).
Twice a year for a week.

Alternatives considered (Describe any alternative features or products you've considered).

Adding each host separately but it's a lot of additional work for a lot of redises and enlarges list of redises enormously.

Additional information (Add any other context or details here).

Could be related to https://github.com/redis/RedisInsight/issues/2809 as it is in area of enhancing redis cluster support. Also https://github.com/redis/RedisInsight/issues/3035 is somehow connected because slaves are missing from the list. If somebody wanted to enhance cluster support overall such trio is quite nice.

Start by reviewing the related issues 2809 and 3035, then inspect the existing Redis cluster connection handling. Done means one cluster entry can specify multiple hosts and Redis Insight remains reachable when one node is down, without requiring separate entries for every host.
