Extract hook based tests to a separate file

[zastrowm]

Description

Motivation: As I started adding new hook events, it started to become difficult to identify hook-based tests from general-purpose agent tests. To simplify things, I split out hook-related tests into test_agent_hooks.

Also updated the hook tests verify each hook-event individually to be more readable/easier to debug.

The intention of the following format is to make it easier to understand as we add new hook-events:

    events = hook_provider.get_events()
    assert len(events) == 2

    assert events.popleft() == StartRequestEvent(agent=agent)
    assert events.popleft() == EndRequestEvent(agent=agent)

when adding a new event, we sould increment the count but still keep the other events as-is:

    events = hook_provider.get_events()
    assert len(events) == 3

    assert events.popleft() == StartRequestEvent(agent=agent)
    assert events.popleft() == SomeMiddleEvent(agent=agent)
    assert events.popleft() == EndRequestEvent(agent=agent)
