be2a2ab6a [tests] fix - use rpc_timeout as rpc timeout (John Newbery)
Pull request description:
Some additional tidyups after the introduction of TestNode:
- commit 1 makes TestNode use the correct rpc timeout. This should have been included in #11077
- commit 2 separates `add_node()` from `start_node()` as originally discussed here: https://github.com/bitcoin/bitcoin/pull/10556#discussion_r121161453 with @kallewoof . The test writer no longer needs to assign to `self.nodes` when starting/stopping nodes.
- commit 3 adds a `set_test_params()` method, so individual tests don't need to override `__init__()` and call `super().__init__()`

08ce33f8e qa: Move wait_until to util (MarcoFalke)
Pull request description:
This moves `wait_until` to `util.py` to make it generally available to python tests.
Also, `wait_until` now takes an optional lock that is acquired while testing the predicate.
Previously the lock was always acquired, even when it was not necessary, cf. `disconnect_ban.py`.

faa76d1b7 qa: Fix inv race in example_test (MarcoFalke)
Pull request description:
There have been intermittent test failures on this script.
```py
File "./test/functional/example_test.py", line 216, in run_test
assert_equal(block, 1)
AssertionError: not(2 == 1)
```
Probably the simplest way to fix them is overriding the `on_inv` method, so that no "colliding" getdata for the blocks are sent out.
Additionally, all getdata are now sent in a single message.
