[WIP] [RFE] Adding affinity for clusters

[agonzalezrh]

This approach uses two new parameters in the request:

• affinity_label to assign a label for a sandbox, to be used as a reference

• affinity_type with two possible options:

  • sandbox_cluster: it will use the sandbox with same label but without affinity_type to decide which cluster to be used
  • affinity_cluster: it will use affinity cluster from the sandbox with same label

  Example:

  "service_uuid": "c1aaf117-c5ac-4bc3-bcd7-b4d4de16e9fe",
  "resources": [
    {
      "kind": "OcpSandbox",
      "count": 1,
      "affinity_label": "main",
      "cloud_selector": {
         "cloud": "cnv",
         "virt": "yes",
         "purpose": "dev",
         "hcp": "no"
      }
    },
    {
      "kind": "OcpSandbox",
      "count": 1,
      "affinity_label": "main",
      "affinity_type": "affinity_cluster",
      "cloud_selector": {
         "cloud": "cnv",
         "purpose": "dev"
      }
    }
  ],
  "annotations": {
    "guid": "13012025",
    "env_type": "ocp4-cluster",
    "namespace_suffix": "ocp4-cluster"
  }
  }
  
  

If the first sanndbox is hosted on ocpvdev01, the second sandbox it will search in the database a cluster with affinity to ocpvdev01 (ocpvdev01-hcp01, ocpvdev01-hcp02)..

Replacing affinity_cluster with sandbox_cluster, both sandbox will be in the same cluster
