Add support for MFA

[flippyboy]

When trying to log in using an MFA enabled account, I get the following reply:
Logging in... &{%!e(string=could not find node that matches "input[name=\"SAMLResponse\"]")}

I'm guessing this is because I have MFA enabled on my account.
As MFA is something that everyone should have enabled on their accounts, it would be nice to support it here.

Thanks for filing this feature request @flippyboy. I was able to reproduce this issue, it's indeed happening on MFA enabled accounts. I will try to find some time the enxt days to work on that.

In an ideal world a user would be able to request an API via customer connect, in the same way that they can on network.pivotal.io. This would negate the need for any username or password to be used by vcc. That said I think we'd have to demonstrate signifficant use of vcc to justify the customer connect team doing this work.

I just found out that Customer Connect has the possibility to use an authentication code instead of username + password.

If it is possible to use that in this tool, that would be a nice way of solving the MFA problem

Very interesting, thanks @flippyboy. I'll add this to the backlog, as would hopefully simplify things quite a bit on our side.
