Create a new Site Endpoint

Based on https://gitlab.hzdr.de/hub-terra/sms/frontend/-/issues/350 a backend Endpoint is needed.

• make a specification together with Frontend Team @tim.eder
• Implement the Endpoint
• Implement Tests
• merge in Develop

This is the data model I am currently using in the frontend prototype. geom is an array of coordinate tuples. We could save it as a string encoded GeoJSON in the db. It is done like this in the BioMe webgis component. It could look like this:

"{\u0022type\u0022:\u0022MultiLineString\u0022,\u0022coordinates\u0022:[[[13.0467449439711,50.8897275252422],[13.0469384939347,50.8896681546136],[13.0472165032372,50.8896228347039],[13.0474117020844,50.8895774604349]]]}"

export interface ILatLng {
  lat: number,
  lng: number
}

export interface IAddress {
  street?: string
  streetNumber?: string
  city?: string
  zipCode?: string
  country?: string
  building?: string
  room?: string
}

export interface ISite {
  id: string
  label: string
  geom: ILatLng[]
  description: string
  epsgCode: string
  address: IAddress
  archived: boolean
  contacts: IContact[]
  createdAt: DateTime | null
  updatedAt: DateTime | null
  createdBy: IContact | null
  updatedBy: IContact | null
  permissionGroups: : IPermissionGroup[]
  visibility: Visibility
}

The connection between sites and configurations should be handled via the configuration model. Because a configuration can only be part of a single site at a given moment, the configuration model needs to be extended with siteId: string
