Add a functionality to run specific modules with valid domain creds

[wez3]

Add a functionality to run specific modules with valid creds (when specified through CLI-parameters). Can be useful after valid domain creds are gathered. For example the modules:

• auxiliary/scanner/smb/smb_enum_gpp
• auxiliary/scanner/smb/smb_enumshares

I don't think these credentials should be stored in the settings file. This might cause issues as people tend to forget to reconfigure settings per run. I propose either to add a question during start up, and/or hide these questions behind an argument.
