v0.5.0-alpha.3

Here is the third alpha of v0.5.x tree. It includes many improvements including:

• Initial implementation of cluster events. Now users can observe the cluster state by subscribing to cluster.events channel. Olric sends events in JSON format. Sample from redis-cli:

1) "message"
2) "cluster.events"
3) "{\"timestamp\":1648410047096938000,\"source\":\"127.0.0.1:3320\",\"kind\":\"node-left-event\",\"node_left\":\"127.0.0.1:3321\"}"
1) "message"
2) "cluster.events"
3) "{\"timestamp\":1648410056207893000,\"source\":\"127.0.0.1:3320\",\"kind\":\"node-join-event\",\"node_join\":\"127.0.0.1:3321\"}"
1) "message"
2) "cluster.events"
3) "{\"timestamp\":1648410056107344000,\"source\":\"127.0.0.1:3321\",\"kind\":\"node-join-event\",\"node_join\":\"127.0.0.1:3320\"}"

Available events:

• node-join-event
• node-left-event
• fragment-migration-event
• fragment-received-event
