[PSL-1229] pasteld: handle keep-alive connections (#259)

pasteld v2.2.6
 Added separate class to keep information about HTTP Connection.
 Now requests coming from the existing keep-alive http connection create
 only HTTPRequest object without connection info.
 HTTPRequest object lifetime is now limited to http_request_cb callback.
 Save http connections only in unordered_map with client socket as a key (CHttpWorkerContext).
 - added accept error handler.
 - improved logging

 other changes:
  - returned c++20/gcc-11 changes for Linux
  - added Ctrl-C console handler for Windows to shutdown pasteld
  - improved shutdown when pasteld is still in initialization mode (added some checks to exit earlier)
