Support TLS service when "tls-cluster" is not enabled and persist both plain and TLS port in nodes.conf (#12233) Originally, when "tls-cluster" is enabled, `port` is set to TLS port. In order to support non-TLS clients, `pport` is used to propagate TCP port across cluster nodes. However when "tls-cluster" is disabled, `port` is set to TCP port, and `pport` is not used, which means the cluster cannot provide TLS service unless "tls-cluster" is on. ``` typedef struct { // ... uint16_t port; /* Latest known clients port (TLS or plain). */ uint16_t pport; /* Latest known clients plaintext port. Only used if the main clients port is for TLS. */ // ... } clusterNode; ``` ``` typedef struct { // ... uint16_t port; /* TCP base port number. */ uint16_t pport; /* Sender TCP plaintext port, if base port is TLS */ // ... } clusterMsg; ``` This PR renames `port` and `pport` in `clusterNode` to `tcp_port` and `tls_port`, to record both ports no matter "tls-cluster" is enabled or disabled. This allows to provide TLS service to clients when "tls-cluster" is disabled: when displaying cluster topology, or giving `MOVED` error, server can provide TLS or TCP port according to client's connection type, no matter what type of connection cluster bus is using. For backwards compatibility, `port` and `pport` in `clusterMsg` are preserved, when "tls-cluster" is enabled, `port` is set to TLS port and `pport` is set to TCP port, when "tls-cluster" is disabled, `port` is set to TCP port and `pport` is set to TLS port (instead of 0). Also, in the nodes.conf file, a new aux field displaying an extra port is added to complete the persisted info. We may have `tls_port=xxxxx` or `tcp_port=xxxxx` in the aux field, to complete the cluster topology, while the other port is stored in the normal `<ip>:<port>` field. The format is shown below. ``` <node-id> <ip>:<tcp_port>@<cport>,<hostname>,shard-id=...,tls-port=6379 myself,master - 0 0 0 connected 0-1000 ``` Or we can switch the position of two ports, both can be correctly resolved. ``` <node-id> <ip>:<tls_port>@<cport>,<hostname>,shard-id=...,tcp-port=6379 myself,master - 0 0 0 connected 0-1000 ```

To determine when everything was stable, we couldn't just query the nodename since they aren't API visible by design. Instead, we were using a proxy piece of information which was bumping the epoch and waiting for everyone to observe that. This works for making source Node 0 and Node 1 had pinged, and Node 0 and Node 2 had pinged, but did not guarantee that Node 1 and Node 2 had pinged. Although unlikely, this can cause this failure message. To fix it I hijacked hostnames and used its validation that it has been propagated, since we know that it is stable. I also noticed while stress testing this sometimes the test took almost 4.5 seconds to finish, which is really close to the current 5 second limit of the log check, so I bumped that up as well just to make it a bit more consistent.

This PR adds a human readable name to a node in clusters that are visible as part of error logs. This is useful so that admins and operators of Redis cluster have better visibility into failures without having to cross-reference the generated ID with some logical identifier (such as pod-ID or EC2 instance ID). This is mentioned in #8948. Specific nodenames can be set by using the variable cluster-announce-human-nodename. The nodename is gossiped using the clusterbus extension in #9530. Co-authored-by:

This test fails sporadically: ``` *** [err]: Migrate the last slot away from a node using redis-cli in tests/unit/cluster/cli.tcl cluster size did not reach a consistent size 4 ``` I guess the time (5s) of wait_for_cluster_size is not enough, usually, the waiting time for our other tests for cluster consistency is 50s, so also changing it to 50s.

This PR introduces a couple of changes to improve cluster test stability: 1. Increase the cluster node timeout to 3 seconds, which is similar to the normal cluster tests, but introduce a new mechanism to increase the ping period so that the tests are still fast. This new config is a debug config. 2. Set `cluster-replica-no-failover yes` on a wider array of tests which are sensitive to failovers. This was occurring on the ARM CI.

When using cli to add node, there can potentially be a race condition in which all nodes presenting cluster state o.k even though the added node did not yet meet all cluster nodes. this adds another utility function to wait until all cluster nodes see the same cluster size
