MDEV-31465: main.sum_distinct-big and main.merge-big fail with timeout with view-protocol

MDEV-31455: main.events_stress or events.events_stress fails with view-protocol
MDEV-31457: main.delete_use_source fails (hangs) with view-protocol

Fixed tests:
main.sum_distinct-big, main.delete_use_source - disabled view-protocol
for some cases because they use transactions without autocommit
main.events_stress, main.merge-big - disabled service connection
for some queries since it is necessary that the query SELECT pass
in the same session
