* Add base PROXY support implementation * Remove some dynamic memory allocations * Rewrite configuration reading module * Make everything in core connector memory resource aware * Add logs to check is proxy is used * Add a proxy fallback, and read proxy from env * Add config entry to check application * Cleanup includes * Ddd configuration dump to check application * Update rhel8 packages * Fix http headers bug when using proxy server * Fix formatting * Fix bad optional access * Fix configuration check regresion * Fix memory management issue, remove strict allocators and make connector more polite to memory overflow errors * Fix initialization of core handler
