Add did core structure support in resolving service endpoints function

[mishasizov-SK]

Need to add a support of the next structure of services in DID doc:

"service": [
    {
      "id": "#linkeddomains",
      "type": "LinkedDomains",
      "serviceEndpoint": {
        "origins": [
          "https://did.rohitgulati.com/"
        ]
      }
    },
    {
      "id": "#hub",
      "type": "IdentityHub",
      "serviceEndpoint": {
        "instances": [
          "https://hub.did.msidentity.com/v1.0/a492cff2-d733-4057-95a5-a71fc3695bc8"
        ],
        "origins": []
      }
    }
  ]
