v1.1.0

• added NGINX test
• edge and level triggered variants for epoll tests (level should be faster in this particular test)
• new hybrid server variant of ARSD (thanks Adam)
• added TCP_NODELAY to listen socket in some tests (client sockets should derive this)
• make response sizes even for all tests
• errors and response size columns are printed out only when there's some difference as they are pretty meaningless otherwise
• switch to wrk load generator as a default (hey is still supported) - as it is less resource demanding and gives better control over client connections and it's worker threads
