This PR implements the following new nodetool commands: * netstats * tablehistograms/cfhistograms * proxyhistograms All commands come with tests and all tests pass with both the new and the current nodetool implementations.

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.
