REGTESTS: add QUIC test for max-total streams setting

Add a new QUIC regtest to test the new frontend stream.max-total
setting.

This test relies on two haproxy instances, as QUIC client and server.
New setting stream.max-total is set to 3 on the server side. In total, 6
requests are performed, with a check to ensure that a new connection has
been reopened for the last ones.
