Dedicated mechanism for requesting a large file limit

[dstufft]

Right now we limit uploads to 60MB in size, but some projects legitimately have a hard time fitting themselves into that size. With Warehouse we have the ability to increase that limit on a per project basis, however doing that currently involves manually running some SQL.

What would be great is a UI (logged in on the project admin page) that allows maintainers to request a limit increase that includes what limit they would like as well as a place for them to justify the increase. We could then have a similar page in the Warehouse admin that allows us to go through and hit approve or deny on each request.

Until we have this, would it make sense to do the following?

• Add an issue template for limit requests, requesting the relevant information.
• Add an FAQ entry when folks hit the limit, that points to that issue template.
• Update the error message from PyPI for upload limits to point to the FAQ entry.

@pradyunsg I agree.
