faa8d9581 [qa] TestNode: Add wait_until_stopped helper method (MarcoFalke)
Pull request description:
This adds a helper method `wait_until_stopped` to the `TestNode` class. This should prevent numerous `time.sleep()` over all places.
Additionally, the timeout behavior is restored. (Was removed by the introduction of `TestNode`.)
This should prevent tests from running indefinitely by accident.

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__()`

c6ec4358a [tests] Add bitcoin_cli.py test script (John Newbery)
b23549f6e [tests] add TestNodeCLI class for calling bitcoin-cli for a node (John Newbery)
Pull request description:
We don't test bitcoin-cli at all. That means that we can miss inconsistencies between the bitcoin-cli client and the RPC interface, such as #10698 and #10747. It also means that the various bitcoin-cli options and features are untested and regressions could be silently introduced.
Let's fix that.
This PR adds bitcoin-cli testing in the python functional test_framework:
1. Add a bitcoin_cli.py test script that tests bitcoin-cli. At the moment it only tests that the result of `getinfo` is the same if you run it as an RPC or through bitcoin-cli, but can easily be extended to test additional bitcoin-cli features
**EDIT: `--usecli` option is moved to a separate PR. This PR now only covers the bitcoin_cli.py test.**
2. ~Add a `--usecli` option to the test framework. This changes the test to use bitcoin-cli for all RPC calls instead of using direct HTTP requests. This is somewhat experimental. It works for most tests, but there are some cases where it can't work transparently because:~
- ~the testcase is asserting on a specific error code, and bitcoin-cli returns a different error code from the direct RPC~
- ~we're sending a very large RPC request (eg `submitblock`) and it can't be serialized into a shell bitcoin-cli call.~
~I think that even though `--usecli` doesn't work on all tests, it's still a useful experimental feature. Future potential enhancements:~
- ~enhance the framework to automatically skip tests that are known to fail with bitcoin-cli if the `--usecli` option is used.~
- ~run a subset of tests in Travis with `-usecli`~
This builds on and requires the `TestNode` PR #10711 . As an aside, this is a good demonstration of how tidy it is to add additional features/interfaces now that test node logic/state is encapsulated in a TestNode class.
Addresses #10791

2b4ea52 [tests] fix timeout issues from TestNode (John Newbery)
Pull request description:
Fixes a couple of bugs from the introduction of TestNode:
- test scripts were no longer able to specify a custom timeout for
starting a node. Therefore tests with nodes that take a long time to
start up (eg pruning.py) would fail.
- the test for whether a node has failed on start up was broken
by changing 'assert x is None' to 'assert not x'. Since
subprocess.poll() can return None (indicating the node is still running)
or 0 (indicating the node exited with return code 0), this was a
regression.

c1470a0 test: Increase initial RPC timeout to 60 seconds (Wladimir J. van der Laan)
Pull request description:
When running the tests locally with a parallelism of 4 on an otherwise busy system, RPC can take quite a wait to come up.
With the current timeout tests often fail with "Unable to connect to bitcoind".
Change the timeout to 60 seconds just to be safe.
