Requests with KSqlDbRestApiClient can result in 431 error codes #80

I have a BackgroundService that is responsible for opening a push query and making sure it stays alive. I do this by executing SHOW QUERIES; to the /ksql endpoint and verify that the query is still running. I have noticed since this runs on a loop that after awhile I will begin to receive 431 error codes indicating that the header is too large on my request. I believe the issue is here and is due to the value being appended to the existing header since there is already a value present.

An example output to my console when I turn on trace logging

      Sending HTTP request POST /ksql

trce: System.Net.Http.HttpClient.IHttpClientFactory.ClientHandler[102]
