Cluster provisioning part 1

[nsricardor]

This pull request implements the provisioning of compute clusters, integrating the latest version of the region service with a shift from physical networks to a more flexible generic network model. While the core provisioning functionality is in place, there are a few features still pending implementation, such as the image selector logic, OpenAPI cluster status support, and the logic to provide custom configuration options post-provisioning.

Looks relatively small, you're next on my list!

I think other than my pedantry, it's good to test on Monday. Looking forward to it!

Okay so you can now do...

import (
  "github.com/spjmurray/go-util/pkg/set"
)

func foo() {
  // Nice data types!
  actual := set.New[string]()
  required := set.New[string]()

  for _, rule := range rules {
    actual.Add(rule.ID)
  }

  ... etc
  
  // Even nicer Cantor style set theory jazz!
  return required.Difference(actual), actual.Difference(required)
}

I'll get it updated before your Monday starts ;)

You could even go as far as something like...

type RuleList []Rule

func (l RuleList) IDs() iter.Seq[string] {
  return func(yield func(s string) bool) {
    for _, r := range l {
      if !yield(r.ID) {
        return
      }
    }
  }
}

then...

actual := set.New(slices.Collect(rules.IDs())...)

some of the new stuff in Go is bloody lovely 😻

Wing it, I can "create" a cluster in the UI and it says provisioned, I'll add in issues as I encounter them!
