Tezlink/Tezt Cloud: refactor running the TzKT processes
Contributes to L2-268.
Rebases on !18896 (merged).
Why
The code looks a bit better like this. That's an opinion of course.
Manually testing the MR
Run
make -f etherlink.mk build
dune exec tezt/tests/cloud/main.exe -- TEZLINK --dockerfile-alias tezlink --localhost -v
before/after and do whatever you want to convince yourself that nothing has changed.
