WL#17224: TELEMETRY IN COMMUNITY EDITION

Migrate the enterprise "telemetry" component to the community edition.

Refactoring task, handled as a WL fast track.

NF-1: Move the telemetry_client plugin from enterprise to community.

NF-2: Move the test_telemetry_resource_provider component from enterprise to community.

NF-3: Move the test_telemetry_secret_provider component from enterprise to community.

NF-4: Move the telemetry component from enterprise to community.

This task is internal refactoring, to move code:

• from internal/xxx
• to xxx

Listing work to help scope the task.

• move third party libraries from "internal/extra" to "extra" (json, opentelemetry-proto, opentelemetry-cpp)

• move "internal/cmake" telemetry helpers to "cmake"

• move "internal/components/telemetry" to "components/telemetry"

• move "internal/plugin/telemetry_client" to "plugin/telemetry_client"

• move associated MTR test suites accordingly

• make sure the doxygen build is clean, as it contains new community code.

• adjust enterprise and community packaging

• document new build options (WITH_MYSQL_CLIENT_TELEMETRY, WITH_MYSQL_SERVER_TELEMETRY) in the community refman

• plan blogs to roll out
