Azat Khuzhin 1af02f02bd Add a test for INSERT w/o user in interserver mode
v2: ensure that the test fails with the version w/o fix
v3: force connect by modifying config and reload it
v4: add comments

# INSERT w/o initial_user
#
# Buffer() flush happens with global context, that does not have user
# And so Context::user/ClientInfo::current_user/ClientInfo::initial_user will be empty
#
# This is the regression test for the subsequent query that it
# will not use user from the previous query.
#
# The test a little bit complex, but I will try to explain:
# - first, we need to execute query with the readonly user (regualar SELECT),
# and then we will execute INSERT, and if the bug is there, then INSERT will
# use the user from SELECT and will fail (since you cannot do INSERT with
# readonly=1/2)
#
# - the trick with generating random priority (via sed) is to avoid reusing
# connection from n1 to n2 from another test (and we cannot simply use
# another pool after ConnectionPoolFactory had been added [1].
#
# [1]: https://github.com/ClickHouse/ClickHouse/pull/26318
#
# We need at least one change in one of fields of the node/shard definition,
# and this "priorirty" for us in this test.
#
# - after we will ensure that connection is really established from the context
# of SELECT query, and that the connection will not be established from the
# context of the INSERT query (but actually it is a no-op since the INSERT
# will be done in background, due to insert_distributed_sync=false by
# default)
#
# - if the bug is there, then FLUSH DISTRIBUTED will fail, because it will go
# from n1 to n2 using previous user.
#
# I hope that this will clarify something for the reader.
