[FEA] Provide tracing and performance statistics gathering capability in App SDK

[MMelQin]

Is your feature request related to a problem? Please describe.
With the use of logging library, application execution logs can be gathered at various logging level per configuration. However, with the maturing of the App SDK, especially when venturing into clinical deployment (IRB'ed), there are stronger needs to provide additional insights into the application execution, e.g. activity audits, performance metrics both in terms of latency and ideally result accuracy.

This is important when AI applications are deployed and used in imaging workflow, as the IT/PACS admins always need to have insights into the latency, resource, and clinical performance of the applications, so as to better manage the critical workflow stage for operational, clinical, as well as regulatory requirements.

Describe the solution you'd like
A logging framework that will support pre-defined as well as custom categories of metrics collection, while making the aggregation and delivery of the metrics dynamic and configurable, e.g. records gather could be delivered to the stats gathering agent on the host system that runs the MAP.

Describe alternatives you've considered
Native logging library with logging level combined with defined string literal indicating the categories of information, e.g. default being execution log, "PERF" for elapsed time for blocks of execution, etc.

Additional context

[dbericat]

Right now is defined by the application developer.

Ideally, existing built in operators include performance type logs and support SOLE: what gets executed and what performance.

Define statistics we want to gather.
