InfluxDB 2.1 Incompatibility with Session Cookie

[sbhenderson]

Steps to reproduce:
List the minimal actions needed to reproduce the behavior.

1. Use InfluxDB 2.1
2. Activate any API that uses the signin logic of ApiClient
3. Exception occurs due to a LINQ "Sequence contains no matching element"

Call stack:

System.InvalidOperationException: Sequence contains no matching element
at System.Linq.ThrowHelper.ThrowNoMatchException()
at System.Linq.Enumerable.First[TSource](IEnumerable1 source, Func2 predicate)
at InfluxDB.Client.Api.Client.ApiClient.InitToken()
at InfluxDB.Client.Api.Client.ApiClient.BeforeIntercept(IRestRequest request)
at InfluxDB.Client.Api.Client.ApiClient.InterceptRequest(IRestRequest request)
at InfluxDB.Client.Api.Client.ApiClient.CallApiAsync(String path, Method method, List1 queryParams, Object postBody, Dictionary2 headerParams, Dictionary2 formParams, Dictionary2 fileParams, Dictionary`2 pathParams, String contentType, CancellationToken cancellationToken)

Expected behavior:
Not to throw exception

Actual behavior:
Exception thrown

The reason is that there is no longer a cookie called "session" for InfluxDB OSS. It is now called influxdb-oss-session.

Specifications:

• Client Version: 3.2.0-dev
• InfluxDB Version: 2.1 from Docker
• Platform: Linux
