## Motivation
- Structured logging with proper log levels (TRACE, DEBUG, INFO, WARNING, ERROR, CRITICAL)
- Better performance through compile-time formatting
- Consistent formatting using fmt library
- Runtime log level control via arguments and environment variables
- Easier maintenance and debugging capabilities
## Technical Details
- Added spdlog as a submodule and integrated it into CMake build system
- Created new `rocprofiler-systems-logger` library wrapping spdlog functionality
- Replaced custom logging macros (`ROCPROFSYS_VERBOSE`, `ROCPROFSYS_DEBUG`, `ROCPROFSYS_FATAL`, `ROCPROFSYS_REQUIRE`, `ROCPROFSYS_CI_THROW`, etc.) with spdlog equivalents (`LOG_DEBUG`, `LOG_WARNING`, `LOG_CRITICAL`, etc.)
- Implemented log level control through command-line arguments and environment variables
- Converted assertion macros to proper error handling with exceptions and std::abort()
**Thread limit configuration and enforcement: **
* Added a check in `CMakeLists.txt` to ensure `ROCPROFSYS_MAX_THREADS` is at least 128, automatically setting it to 128 with a warning if a lower value is provided.
* Replaced hardcoded thread limit (`allowed_max_threads`) in `pthread_create_gotcha.cpp` with the configurable `ROCPROFSYS_MAX_THREADS` value, ensuring all runtime checks and warnings use the actual configured limit.
**Documentation improvements: **
* Updated the development guide to explain the new thread limit behavior, including how exceeding the limit is handled gracefully, how to configure it, and the build-time validation rules.
**Test updates: **
* Modified thread limit tests to use the configurable `ROCPROFSYS_MAX_THREADS` value instead of a hardcoded limit and expanded the range of tested thread values.
* Increased test timeouts to accommodate larger thread counts and ensure reliability with higher limits.
* Put cached perfetto traces as default one
* Improve cached data and perfetto traces in order to be more aligned with E2E tests
* Addressing PR comments and findings
* Force early instrumentation bundle instantiation
* Sync-up insturumented containers with thread growth data
* Revert ompvv number of host threads to default 8
* Fixed counter track namings for amd-smi
* AIPROFSYST-34 [rocprof-sys] Update documentation describing newly introduced changes to default tracing mechanism
* Consolidate CTests to tests/ folder
* Remove comment
* Consolidate CTests to tests/ folder
* Remove comment
* Separate source code and test code for thread-limit into appropriate folders
* Remove sleeper.cpp and instead use linux sleep cmd
* Merge python-console tests into python-tests
