`test_long_query_timeout_erm` is slow because it has many parameterized
variants, and it verifies timeout behavior during ERM operations, which
are slow by nature.
This change speeds the test up by roughly 3× (319s -> 114s) by:
- Removing two of the five scenarios that were near duplicates.
- Shortening timeout values to reduce waiting time.
- Parallelizing waiting on server_log with asyncio.TaskGroup().
The two removed scenarios (`("SELECT", True, False)`,
`("SELECT_WHERE", True, False)`) were near duplicates to
`("SELECT_COUNT_WHERE", True, False)` scenario, because all three
scenarios use non-mapreduce query and triggers basically the same
system behavior. It is sufficient to keep only one of them, so the test
verifies three cases:
- One with nodes shutdown
- One with mapreduce query
- One with non-mapreduce query

decrease request timeout.
In debug mode, queries may sometimes take longer than the default 30 seconds.
To address this, the timeout value `request_timeout_on_shutdown_in_seconds`
during tests is aligned with other request timeouts.
Change request timeout for tests from 180s to 90s since we must keep the request
timeout during shutdown significantly lower than the graceful shutdown timeout(2m),
or else a request timeout would cause a graceful shutdown timeout and fail a test.
This test verifies the effectiveness of the mechanism for releasing ERM
introduced in this patch series. In test scenario, during processing of
a query in mapreduce service, reads are intentionally blocked by
an injected error. However, when table uses tablets, ERM is now often
released by the mapreduce service, so the topology is not blocked to the
end of the request. As a result, it is possible to add a new node
before the query finishes.

One of pytest parameters in test_long_query_timeout_erm.py was
a CQL query containing spaces and special chars such as '*', '(', ')',
'{', '}'. After upgrading to Fedora 42, the test started to
fail with the error "test.pylib.rest_client.HTTPError: HTTP error 404"
with uri=`http://...[SELECT * FROM {}-True-False].dev.1`.
To prevent from such errors, this commit changes the parameter to
a string without spaces and such special characters.

Some of the tests in the test suite have proven to be more problematic
in adjusting to RF-rack-validity. Since we'd like to run as many tests
as possible with the `rf_rack_valid_keyspaces` configuration option
enabled, let's disable it in those. In the following commit, we'll enable
it by default.
This commit adds a test to verify that a query with long timeout
doesn't block ERM on failure. The motivation for the test is
fixing scylladb#21831.
