Important changes:

[EXPORTER] Gzip compression support for OTLP/HTTP and OTLP/gRPC exporter

#2530

In the OtlpHttpExporterOptions and OtlpGrpcExporterOptions, a new

field called compression has been introduced. This field can be set

to "gzip” to enable gzip compression.
The CMake option WITH_OTLP_HTTP_COMPRESSION is introduced to enable

gzip compression support for the OTLP HTTP Exporter and includes a

dependency on zlib.


[SDK] Change OTLP HTTP content_type default to binary

#2558
[CI] Use platform CMake

#2627

The CI in github no longer install a different version of cmake.
It now always use the cmake provided by the platform.
As part of this change, the script ci/setup_cmake.sh was renamed

to ci/setup_googletest.sh, for clarity, now that this script

only installs googletest.


[SDK] DefaultLogHandler to print to std::cerr, add LogLevel::None

#2622

Change DefaultLogHandler output

Before, the default internal logger, DefaultLogHandler,

used to print to std::cout.
Now, DefaultLogHandler prints errors and warnings to std::cerr,

as expected, while printing info and debug messages to std::cout.
Applications that expected to find the opentelemetry-cpp internal

error log in std::cout may need adjustments, either by looking

at std::cerr instead, or by using a custom log handler.


Additional LogLevel::None

LogLevel::None is a new supported log level, which does not print

any message.
Custom log handlers may need to implement a new case, to avoid

compiler warnings.
Numbering of log levels like OTEL_INTERNAL_LOG_LEVEL_ERROR

has changed, which requires to rebuild, as the SDK ABI differs.
