* add opentracing section and otelCollectorEndpoint * initialize OTLP exporter * pkg/controller: changes for context propagation * pkg/executor: changes for context propagation * pkg/fetcher: changes for context propagation * pkg/router: changes for context propagation * pkg/storagesvc: changes for context propagation * set no default value for otel collector endpoint * update readme and add notes to charts * move common code to pkg/utils/otel * adding fn and env as attributes * don't use otelhttp transport for websocket * URL ignore with common filter UrlsToIgnore Note: The web socket example does not work when using OTEL HTTP. Here is an issue related to that on open-telemetry/opentelemetry-js-contrib. Signed-off-by: Gaurav Gahlot <gauravgahlot0107@gmail.com> Co-authored-by: Sanket Sudake <sanketsudake@gmail.com>
