Add new command `fluvio cluster resume`

[digikata]

On some systems fluvio cluster start can fail to recognize started spus and timeout despite the spus reporting status. (MacOs Sonoma 14.1.2)

Problem

Starting up with multiple spus, creating a topic with replicas higher than 1, then restarting with a different number of spus causes this problem. This can be fixed by starting the cluster with the original start options or a fluvio cluster delete and a fresh fluvio cluster start

$ fluvio cluster start --spus 3
$ fluvio topic create --replication 3 repltopic
$ fluvio produce repltopic
Ok!

$ fluvio cluster shutdown

$ fluvio cluster start

Solution

disallow fluvio cluster start after a fluvio cluster shutdown. Instead add new command for fluvio cluster resume
