test/pylib: increase control connection timeout in cql_is_up

After starting the associated node, ScyllaServer waits until the node
starts serving CQL requests. It does that by periodically trying to
establish a python driver session to the node.

During session establishment, the driver tries to fetch some metadata
from the system tables, and uses a pretty short timeout to do so (by
default it's 2 seconds). When running tests in debug mode, this timeout
can prove to be too short and may prevent the testing framework from
noticing that the node came up.

Fix the problem by increasing the timeout. Currently, after the session
is established, a query is sent in order to further verify that the
session works and it uses a very generous timeout of 1000 seconds to do
so - use the same timeout for internal queries in the python driver.

Fixes: scylladb/scylladb#15898

Closes scylladb/scylladb#15929
