Instead of having a lot of separate fixtures for setting up the page server, the compute nodes, the safekeepers etc., have one big ZenithEnv object that encapsulates the whole environment. Every test either uses a shared "zenith_simple_env" fixture, which contains the default setup of a pageserver with no authentication, and no safekeepers. Tests that want to use safekeepers or authentication set up a custom test-specific ZenithEnv fixture. Gathering information about the whole environment into one object makes some things simpler. For example, when a new compute node is created, you no longer need to pass the 'wal_acceptors' connection string as argument to the 'postgres.create_start' function. The 'create_start' function fetches that information directly from the ZenithEnv object.
