Important changes:

[EXPORTER] GRPC endpoint scheme should take precedence over OTEL_EXPORTER_OTLP_TRACES_INSECURE

#2060

The logic to decide whether or not an OTLP GRPC exporter uses SSL has

changed to comply with the specification:

Before this change, the following settings were evaluated, in order:

OTEL_EXPORTER_OTLP_TRACES_INSECURE (starting with 1.8.3)
OTEL_EXPORTER_OTLP_INSECURE (starting with 1.8.3)
OTEL_EXPORTER_OTLP_TRACES_SSL_ENABLE
OTEL_EXPORTER_OTLP_SSL_ENABLE


With this change, the following settings are evaluated, in order:

The GRPC endpoint scheme, if provided:

"https" imply with SSL,
"http" imply without ssl.


OTEL_EXPORTER_OTLP_TRACES_INSECURE
OTEL_EXPORTER_OTLP_INSECURE
OTEL_EXPORTER_OTLP_TRACES_SSL_ENABLE
OTEL_EXPORTER_OTLP_SSL_ENABLE


As a result, a behavior change for GRPC SSL is possible,

because the endpoint scheme now takes precedence.

Please verify configuration settings for the GRPC endpoint.




[SDK] Add ForceFlush for all LogRecordExporter and SpanExporter

#2000

LogRecordExporter and SpanExporter add a new virtual function

ForceFlush, and if users implement any customized LogRecordExporter and

SpanExporter, they should also implement this function.

There should be no impact if users only use factory to create exporters.
