Multiple base URIs

[sergiobortsov]

Hello!
Sorry if such an issue was already discussed somewhere, but I'd to know if it's possible to use restapi provider for the multiple base URIs in case we need to be able to call different APIs.
I thought this key

terraform-provider-restapi/examples/resources/restapi_object/resource.tf

Line 2 in 2a972ea

provider = restapi.restapi_headers

was designed for something like this to be able to choose which provider to use. But I believe that key was disabled completely, so example file is not up to date.
I'd appreciate any help in this regard.
Thanks
