Merge fideslib into unified-fides

[ThomasLaPiana]

Is your feature request related to a specific problem?

Now that everything is merged into a single project, the additional friction of updating fideslib is no longer worth it since it is no longer enabling code-sharing. Case in point, PRs like this become more complicated as we end up circumventing fideslib altogether instead of trying to fix it properly and cut another release.

Describe the solution you'd like

Copy/pasta, keeping the git history doesn't seem particularly important here given the additional complexity

@NevilleS @seanpreston FYI this is on my mind. That repo is now devoid of its original purpose and should be folded back in (the arms of unified-fides are ever-open to embrace more code)

@ThomasLaPiana I agree, now that fidesctl and fidesops are merged we could move faster by also merging fideslib in. It should be relatively painless to merge in (famous last words right?).

I also agree that keeping the git history would be more trouble than it is worth here.
