Protocol based automatic input handling

[ehsandeep]

Depends on https://github.com/projectdiscovery/nuclei/issues/2253

Please describe your feature request:

As nuclei engine supports multiple protocols that may expect different inputs varies from -

• host
• host:port
• scheme://host:port
• ip
• ip:port
• scheme://ip:port

Currently, nuclei handle input for supported protocol automatically when scheme://host:port is provided, but for a reason listed in https://github.com/projectdiscovery/nuclei/issues/2253, scheme://host:port shouldn't be the ideal input for non HTTP based protocol.

Describe the use case of this feature:

This will eliminate the possibility of invalid inputs from users or having to keep in mind what type of format needs to be provided depending on the type of templates that are running.
