Add --insecure (curl equivalent) flag for tool

[Abhinandan-Khurana]

Currently the tool is trying to validate the x509 certificate first and then scans the HTTP METHODS.
So, sometimes in case of the format - https://$IP_ADDRESS is unable to check to verify the ssl cert and throws the error even though the IP is reachable and URL is reachable while opening via browser or via curl --insecure flag.

Need to add a flag to allow curl --insecure equivalent, so that the tool works for certain invalid certificate IPs as well.
