[BUG] Uncontrolled growth of memory consumption

[XCiteForever]

ECS integration/library project(s) (e.g. Elastic.CommonSchema.Serilog): Elastic.Extensions.Logging

ECS schema version (e.g. 1.4.0): latest

ECS .NET assembly version (e.g. 1.4.2): latest

.NET framework / OS: .NET 8.0 / Any OS

Setting OutboundBufferMaxLifetime to Timespan.Zero will cause memory consumption to continually increase.

Steps to reproduce:
1.
Configure connection as:
services .AddLogging(c => { c.AddElasticsearch(lo => {}, co => { co.BufferOptions.OutboundBufferMaxLifetime = TimeSpan.Zero; }); });

I couldn't quite reproduce this but because TimeSpan.Zero basically causes export buffers of size 1 the inbound channel will never be drained fast enough and so should grow although not bounded.

I opened elastic/elastic-ingest-dotnet#72 to address this.

Will spend some more time trying to reproduce.
