ScyllaCluster.nodelist() was creating new ScyllaNode objects on every
call, so per-node state set via set_smp(), set_log_level(), and
_adjust_smp_and_memory() was lost between calls.
Fix by caching ScyllaNode instances in a list populated by
_add_nodes() using the list returned by servers_add() in populate().
Nodes are assigned monotonically increasing names (node1, node2, ...).
nodelist() simply returns the cached list.
cluster.dtest_alternator_tests.test_slow_query_logging performs
a bootstrap with 768 token ranges.
It works with `me` sstables, which have 2 open file descriptors
per open sstable, but with `ms` sstables, which have 3 open
file descriptors per open sstable, it fails with EMFILE.
To avoid this problem, let's just decrease the number of vnodes
for in the test suite. It's appropriate anyway, because it avoids some
unneeded work without weakening the tests.
(Note: pylib-based have been setting `num_tokens` to 16 for a long time too).
This breaks `bypass_cache_test`, which is written in a way that expects
a certain number of token ranges. We adjust the relevant parameter
accordingly.
And dependencies: get_sstables() and __gather_sstables().
Code is importend verbatim, but doesn't work yet (no users yet either).
Will be patched to work in the next commit.
Extract regex compilation from the stress functions to the module level,
to avoid unnecessary regex compilation repetition.
Add descriptions to the stress functions.
Do not materialize list in `stress_object` for loop. Use a generator expression.
Make `_set_stress_val` an object method.

This reverts commit b0643f8959, reversing
changes made to e8b0f8faa9.
The change forgot to update
sstables_manager::get_highest_supported_format(), which results in
/system/highest_supported_sstable_version still returning me, confusing
and breaking tests.

test_pinned_cl_segment_doesnt_resurrect_data was not moved in #24946 from
scylla-dtest to this repo, because it's marked as xfail (#14879), but
actually the issue is fixed and there is no reason to keep the test in
scylla-dtest.
Also remove unused imports.

Technically, `new_node()`'s `bootstrap` parameter used to mark a node
as a seed if it's False. In test.py, seeds parameter passed on start of
a node, so, save it as `ScyllaNode.bootstrap` attribute to use in
`ScyllNode.start()` method.
The current implementation of dtest shim use `server_id` to format a
name of a node in a cluster. This is a difference in behavior with dtest.
Some of dtests use code like `cluster.nodes()["node1"]` to get access
to a node object. This commit changes it to be more consistent with
dtest.
Use universalasync library to make test.py async code compatible
with synchronous code of dtest/ccm
Also, copied unmodified error_example_test.py from dtest as an example.
Run the test in `dev` mode only.
