Publish RFCs to github pages

[mtreinish]

Now that we have an RFCs repo once we start merging RFCs we need to have a place to host them. We should add hosting via github pages so we can see the rendered output of the RFCs.

Some are currently in .md and some in .ipynb format. Can both be published? I think some people are more comfortable with one format over the other.

We only have a template for doing this in markdown: https://github.com/Qiskit/rfcs/blob/master/0000-template.md which I assumed was going to be the only format we'd use for these. But, if we want to also accept rfcs in jupyter it's pretty easy to support that too. We can just convert it to markdown as part of a build step, nbconvert does this. So there shouldn't be a problem with that.

But, before we start doing any rfcs as a jupyter notebook we should probably document the expected format for those submissions so that have a standardized method for doing it.

I think having RFC in qiskit.org (maybe as part of the documentation?) it would be good.
