VCC broken after transition to Broadcom

[jhg03a]

Describe the bug

The base_url used no longer functions and account structures are completely different. Additionally it seems Broadcom accounts may have MFA requirements now that weren't there before.

Reproduction steps

Try and use vcc

Expected behavior

It to work again

Additional context

I realize this isn't actually this repo's fault, but I wanted to raise an issue here as well to associate with a new release.
