Add excludeMembers (blacklist) support to all groups

Fixes #5153

Added excludeMembers property to GroupTraits. It is an array of strings of excluded group and item names. A group or item name that appears in this list will not be shown to the user. This is case-insensitive and will also apply to all child/nested groups

Example

{
  "catalog": [
    {
      "type": "sdmx-group",
      "name": "Pacific Data Hub .Stat",
      "url": "https://stats-nsi-stable.pacificdata.org/rest",
      "excludeMembers": [
        "population",
        "Balance of payments"
      ]
    }
  ]
}

Looks great @nfs!

I know it was already in v8 but if it is not too difficult now then maybe we should replace blacklist with excludeList?

Thanks @na9da - yep I'll rename it to something like excludeMembers
