It looks like metadata is ignored and instead we should set the grpc.primary_user_agent channel option instead. User-agent will change from: grpc-python/1.71.0 grpc-c/46.0.0 (linux; chttp2) to: OTel-OTLP-Exporter-Python/1.34.1 grpc-python/1.71.0 grpc-c/46.0.0 (linux; chttp2)

Description
It looks like metadata is not used for setting http User-agent header when using the grpc exporter and instead we should set the
grpc.primary_user_agent
channel option instead. User-agent will change from:grpc-python/1.71.0 grpc-c/46.0.0 (linux; chttp2)
to:
OTel-OTLP-Exporter-Python/1.34.1 grpc-python/1.71.0 grpc-c/46.0.0 (linux; chttp2)
Fixes #4657
