Add redirects for old election profile page links

[lbeaufort]

What we're after: After changing the design of the election profile pages, we changed the way data is organized in tabs on each election page. Unfortunately, the old links are still available and so we need to go back and add redirects for the old election profile page deep links.

The old links that are affected include:
/?tab=totals
/?tab=contributions
/?tab=spending-by-others

This applies to all past /data/elections/senate, /house, and /president pages.
Example: https://www.fec.gov/data/elections/president/2012/?tab=contributions

We should add redirects for the old election profile page deep links.

@patphongs could you also take a look at this ticket to see if we need to update the work or the link?

[AmyKort]

Oh wait. Is this the ticket to update the links?

[patphongs]

@AmyKort Yes this is the one, I'm going to move it to fec-cms, since this actually needs to be done within the urls in python since nginx does not have the capabilities to pass arguments through to the resultant URL.

Issue moved to fecgov/fec-cms #2188 via ZenHub
