add OpenTelemetry architecture image

[viennaa]

Thanks for tackling this.

Can you check the resolution of the image? It seems rather low, when looking at it in a dedicated tab. Also please select a white background, as the kubernetes logo is in front of a transparent background.

I would split the picture a little more. Like so:
Have the collector part with the processors only and the receivers and exporters are left and right of the collector box, no?

Technically these are external components which are pushing to the collector with OTLP. Then the Processor/Pipelining part starts. Then they are shipped to other external components (OpenSearch, Prometheus).
