Michał Chojnowski 9280a039ee test/cluster/dtest: reduce num_tokens to 16
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.

Scylla in-source tests.

For details on how to run the tests, see docs/dev/testing.md

Shared C++ utils, libraries are in lib/, for Python - pylib/

alternator - Python tests which connect to a single server and use the DynamoDB API unit, boost, raft - unit tests in C++ cqlpy - Python tests which connect to a single server and use CQL topology* - tests that set up clusters and add/remove nodes cql - approval tests that use CQL and pre-recorded output rest_api - tests for Scylla REST API Port 9000 scylla-gdb - tests for scylla-gdb.py helper script nodetool - tests for C++ implementation of nodetool

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).

To add a new folder, create a new directory, and then copy & edit its suite.ini.
