Consider unifying our benchmark implementation with the TechEmpower one

[roji]

We currently have two implementations of e.g. TE platforms: one here, and one in the TechEmpower repo. The code is mostly the same, but there are some differences; this leads to constant laborious synchronization of the two, to keep them from diverging etc.

Why not have just a single source base, which we can sync by just copying code wholesale from here to there?

Note that there are two main data-related differences:

• We have Dapper and EF, the TechEmpower code doesn't.
• The TechEmpower code has MySQL (behind #ifs), we don't.

We can unify to have everything, but not necessarily run e.g. Dapper/EF at TechEmpower.

All in support of making it easier to keep our TechEmpower entries and this repo synced. I figure we'll do that as part of the work to deprecate the old benchmarks app implementation and replace it with the new individual apps.
