The perf-simple-query tests were not restricted on CPU count,
so on a 96-CPU machine, they would run on 96 CPUs, and time out
in debug mode.
All restrict memory usage and add --overprovisioned so that
pinning is disabled. Apply that to all tests.
Closesscylladb/scylladb#28821
Add --continue-after-error true to perf-cql-raw and perf-alternator
tests, and --stop-on-error false to perf-simple-query test, so that
tests don't abort on the first error.
Reason for this is that tests are flaky with example failure:
Perf test failed: std::runtime_error (server returned ERROR to EXECUTE)
When CPU is starved on CI we can return timeouts and/or other errors.
The change should make tests more robust on the expense of smaller test
scope. But those tests were written mostly to test startup sequence
as it differs from Scylla's starup.
Fixes https://scylladb.atlassian.net/browse/SCYLLADB-759Closesscylladb/scylladb#28767
It checks if all workloads can be properly
executed with succesfull startup and teardown.
Especially testing alternator in remote mode is important
because it's invoked like this during pgo training in pgo.py.
Test runtime:
Release - 24s
Debug - 1m 15s
Test time consists mostly of Scylla startup in various modes.
