Preconfigured server group for CRUD

[gramian]

Given the new security access types (updateSecurity, updateSchema, updateDatabaseSettings) should there be a new group pre-configured in config/server-groups.json for just CRUD, ie.:

{
  "databases": {
    "*": {
      "groups": {
        "crud": {
          "access": [],
          "resultSetLimit": -1,
          "types": {
            "*": { "access": ["createRecord", "readRecord", "updateRecord", "deleteRecord"] }
          }
        }
      }
    }
  }
}

This would close the gab between admin and readonly.

Thanks for considering this proposal
