Add option to always ask OTP with a profile

[jithk]

I had issues with my company VPN, where the OTP dialog never pops up. I added an option to always show the OTP dialog. This will send the final passwords as <password>,<otp> format as needed by the FortiVPN

Thanks, will look into this. The OTP dialog only shows when a specific keyword is found on openfortivpn output.

For example: https://github.com/theinvisible/openfortigui/issues/103 was missing the "one-time password:" keyword so OTP never showed up. Just add a line with the keyword (see https://github.com/theinvisible/openfortigui/commit/9879dc81f8770db6ea6b3e1a61dd2d00b42c6e1b) or you can send me your specific output.

Our network supports multiple methods of 2FA (OTP being just one of them) It wont show any option even in openfortivpn to enter the otp. The server expects password+opt to be given together each time.

Here is my output from openfortivpn

Thanks, will review this. We have only TOTP here in production, so will rely on your information.
