Important changes

[API/SDK] Provider cleanup

#2664

Before this fix:

The API class opentelemetry::trace::Tracer exposed methods such

as ForceFlush(), ForceFlushWithMicroseconds(), Close()

and CloseWithMicroseconds().
These methods are meant to be used when configuring the SDK,

and should not be part of the API. Exposing them was an oversight.
Two of these methods are virtual, and therefore part of the ABI.


After this fix:

In OPENTELEMETRY_ABI_VERSION_NO 1, nothing is changed,

because removing this code would break the ABI.
In OPENTELEMETRY_ABI_VERSION_NO 2, these methods are moved

from the API to the SDK. This is a breaking change for ABI version 2,

which is still experimental.


In all cases, instrumenting an application should not

invoke flush or close on a tracer, do not use these methods.



Breaking changes

[API/SDK] Provider cleanup

#2664

Before this fix:

SDK factory methods such as:

opentelemetry::sdk::trace::TracerProviderFactory::Create()
opentelemetry::sdk::metrics::MeterProviderFactory::Create()
opentelemetry::sdk::logs::LoggerProviderFactory::Create()
opentelemetry::sdk::logs::EventLoggerProviderFactory::Create()

returned an API object (opentelemetry::trace::TracerProvider)

to the caller.




After this fix, these methods return an SDK level object

(opentelemetry::sdk::trace::TracerProvider) to the caller.
Returning an SDK object is necessary for the application to

cleanup and invoke SDK level methods, such as ForceFlush(),

on a provider.
The application code that configures the SDK, by calling

the various provider factories, may need adjustment.
All the examples have been updated, and in particular no

longer perform static_cast do convert an API object to an SDK object.

Please refer to examples for guidance on how to adjust.
If adjusting application code is impractical,

an alternate and temporary solution is to build with option

WITH_DEPRECATED_SDK_FACTORY=ON in CMake.
Option WITH_DEPRECATED_SDK_FACTORY=ON will allow to build code

without application changes, posponing changes for later.
WITH_DEPRECATED_SDK_FACTORY=ON is temporary, only to provide

an easier migration path. Expect this flag to be removed,

as early as by the next release.



Notes on experimental features

#2372

introduced MeterProvider::SetExemplar() which accepts an

ExemplarFilterType enumeration with kAlwaysOff, kAlwaysOn and

kTraceBased.
