add conn deadlines and fix retry logic in auto mode

[tarunKoyalwar]

Description

• follow up of Timeout not respected in certain conditions #263 nuclei getting stuck with running ssl template nuclei#3813
• adds deadline (both read and write) to every connection
• implements retry counter in auto mode
  • auto mode does fallback using all available implementations but it is not counted as retry which causes issues related to ^
  • now all fallbacks connections in auto mode are tracked as retry

POC

• setup up open port

 $  sudo nc -dkl 440 
Password:

• run tlsx aganist this port

$  cmdutil ./tlsx -u localhost -p 440 -v
