This is series starts conversion of the gossiper to use host ids to
index nodes. It does not touch the main map yet, but converts a lot of
internal code to host id. There are also some unrelated cleanups that
were done while working on the series. On of which is dropping code
related to old shadow round. We replaced shadow round with explicit
GOSSIP_GET_ENDPOINT_STATES verb in cd7d64f588
which is in scylla-4.3.0, so there should be no compatibility problem.
We already dropped a lot of old shadow round code in previous patches
anyway.
I tested manually that old and new node can co-exist in the same
cluster,

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.
