* Refactor SimpleRingBuffer
- Use std::allocator for memory management
- Add destructor to properly destroy elements and prevent memory leaks
- Remove incorrect modulo in iterator increment
- Fix iterator post-increment operator returning reference
- Use constraints (std::constructible_from) for push/emplace
- Add size() and clear() methods
* tests: fix build and avoid NodeInfoWrapper copy
The copy constructor for SimpleRingBuffer is explicitly disabled in
src/common/utils/SimpleRingBuffer.h. Since NodeInfoWrapper contains
a SimpleRingBuffer, it is also non-copyable.
This commit optimizes the MgmtdOperator tests to use pointers instead
of object copies when retrieving NodeInfoWrapper, avoiding build
failures caused by dereferencing and copying.
* Deprecate usage of boost::filesystem::load_string_file and save_string_file
* some other deperated functions
* remove complete()
* normal, save, load
