SDK Info Exposure Rework (status/details, wait, error-handling, etc.)

[Maxusmusti]

Merge both cluster.status() and cluster.is_ready() into one one function (likely still called status). This will tell the user exactly where in the process of setup their cluster is currently (whether still in AppWrapper stages or in Ray stages). Then, there will be a second function called cluster.details() that will output the cluster information like all of the specs, worker count, uri, active/inactive, etc. (what we currently see when calling cluster.status() on a fully set-up cluster).
