Can't set Timeout via Microsofr Dependency Injection for sync methods

[petr-fleischmann]

Hi,
I can't set Timeout interval when I initialize SOLR via Microsoft.Extensions.DependencyInjection (ASP.NET core)
as services.AddSolrNet<Person>("http://localhost:8983/solr/person");. Method AddSolrNet has second paremeter SolrNetOptions options but HttpClient.Timeout is used only for Async methods. How can I set Timeout for sync methods ? ? Maybe new property in SolrNetOptions.Timeout for SolrConnection ? Btw. default timeout is 100s.

file: AutoSolrConnection.cs:
Async:

` public async Task<Stream> PostStreamAsStreamAsync(string relativeUrl, string contentType, Stream content, IEnumerable<KeyValuePair<string, string>> getParameters, CancellationToken cancellationToken)
        {
            var u = new UriBuilder(ServerURL);
            u.Path += relativeUrl;
            u.Query = GetQuery(getParameters);

            var sc = new StreamContent(content);
            sc.Headers.ContentType = System.Net.Http.Headers.MediaTypeHeaderValue.Parse(contentType);

            var response = await HttpClient.PostAsync(u.Uri, sc);

            if (!response.IsSuccessStatusCode)
                throw new SolrConnectionException($"{response.StatusCode}: {response.ReasonPhrase}", null, u.Uri.ToString());

            return await response.Content.ReadAsStreamAsync();
        }`

Sync: (Doesn't use HttpClient from SolrOptions)
public string PostStream(string relativeUrl, string contentType, Stream content, IEnumerable<KeyValuePair<string, string>> getParameters) => SyncFallbackConnection.PostStream(relativeUrl, contentType, content, getParameters);

Thank you for your help
