Elastic scaling: add e2e test (#3929)

On top of https://github.com/paritytech/polkadot-sdk/pull/3879 I've also moved the previous test where we ensure multiple cores per para doesn't break non elastic parachains. --------- Signed-off-by: Andrei Sandu <andrei-mihail@parity.io> Co-authored-by: Javier Viola <363911+pepoviola@users.noreply.github.com>
