Pull request overview
This PR aims to prevent NetworkManager event publishing from blocking (and potentially deadlocking/crashing) caller threads by offloading notification delivery onto Thunder’s default Core::IWorkerPool.
Changes:
- Introduces a worker-pool based event dispatch path (
dispatchEvent+Job) and routes existing NetworkManager notifications through it. - Updates plugin/legacy
.conf.intemplates to use new CMake-configurable*_AUTOSTARTvalues and removes legacy.configtemplates. - Updates the unified plugin targets to build with
CXX_STANDARD 17.

changed the title
Reason for change: All the NetworkManager Events are published from the calling thread context; somethings are from NMEvent, NMThread, somethings are from Connectivity thread and WiFiQualityMonitoring thread. When consumer is not responding properly, this will lead to extended lock & Sometimes Gnome NetworkManager Crash. To avoid this, all the events are sent thro dedicated eventing thread. NOTE: The Thread::WorkerPool that is default created by the Thunder is always using the main thread when available even though worker pool is available. So this is of no use. Test Procedure: Verify All the Networking Events Risks: Medium Signed-off-by: Karunakaran A <karunakaran_amirthalingam@cable.comcast.com
