Make a plan to remove outdated elecfil/ pages and files from transition

[dorothyyeager]

Summary

What we are after:
We are getting things off of transition. Recently the electronic filing team asked us to update old links. We did that in #3893 , but even better, we should find them, identify redirects for them and put those in.

Related issues

• Update link on EFO pages #3893 - Update efiling password link

Action Items

• Review all the files in the elecfil/ directory on transition and determine if they already have a home we can redirect to in https://efilingapps.fec.gov/ (or are redirecting to). Add to spreadsheet
• Confirm proposed redirects with EFO team (Ryan and Ken)
• Once confirmed, put in PR for the EFO redirects
• For files we are already redirecting, need to add them to the take-down list in next step.
• redirects merged and deployed by @patphongs
• Test redirects and make a ticket to take down the files.

Completion criteria

• Old files redirect to current content found at https://efilingapps.fec.gov/ and related pages
• Links on H4CC pages are updated as needed

I've sent the proposed redirects to the eFiling team.

In two cases, important files are on transition. We may end up needing to create one Wagtail page and upload one .zip file. It's possible that EFO may want to do this themselves on their own page. TBD when I hear back from them.

Met with EFO and their contractor who confirmed that everything has been moved into their new set up or onto the FECfile page in H4CC. We won't need to upload or create anything and can move forward with the redirects.

Have put the redirects in with other redirects for another GH ticket in one PR - fecgov/fec-proxy#178.

Redirects are working and we'll take down this directory in #3967.
