[GenericInterface] 2FA was added

[CallMeFlanby]

Proposed change

Added 2FA to the generic interface, allowing (but not forcing) by default the use of 2FA.
Currently, if an account has 2FA activated, this cannot be used with the REST API.
Not breaking change as users, that don't have 2FA will not be affected by this change.

Type of change

• '1 - 🚀 feature' - New feature (which adds functionality to an existing integration)

Found issue #437 related to this.

@CallMeFlanby I like this idea, but it should also work with the optional usage of HTTP headers. See https://github.com/znuny/Znuny/blob/dev/Kernel/GenericInterface/Transport/HTTP/REST.pm#L231

Can you add this to?

I hope it was correct. Somehow however I had to create a new pull request after I changed the name of my branch. Please check #502 now.
