Backward compatibilty tests

[PSeitz]

We could consider to extend the python tests for compatibly tests between quickwit versions. We already have the notion of engine to differentiate between quickwit and elasticsearch.

For that we would need to extend the script to:

• Install multiple Quickwit versions (engine)
  • cargo install from commit hash?
    • We can't install it as e.g. quickwit_old currently cargo install --name: install with a renamed executable rust-lang/cargo#12366)
    • Maybe just copy the compiled binary to quickwit_old
  • Download from a precompiled place ?
• Add a mechanism to execute different queries for each engine
