* Make role param resolution follow the role dependency chain, rather
than using all roles within the play
* Also move params to be merged in after role vars in general, to match
our variable precedence rules
* Changes to the way var lookup is done in role helper methods for
get_vars(), get_inherited_vars(), and get_role_params() to make the
above possible without trampling on previously merged vars
Fixes#14472Fixes#14475
On some switches, starting an SSH connection and immediately calling
recv() will result in a connection timeout. The switch requires some
input on the channel before it provides any prompt.
As such, this patch sends an empty command immediately upon connection,
triggering the switch to send a prompt which the shell can then
interpret.

* Unit tests exposed a problem where nested blocks did not correctly
hit rescue/always portions of parent blocks
* Cleaned up logic in PlayIterator
* Unfortunately fixing the above exposed a potential problem in the
block integration tests, where a failure in an "always" section may
always lead to a failed state and the termination of execution
beyond that point, so certain parts of the block integration test
were disabled.
* fetch_url shouldn't both accept follow_redirects and support follow_redircts via module.params
* Default follow_redirects for open_url should be 'urllib2'
* Add redirect test for get_url
main_q is not used anywhere in the codebase.
It is created in TaskQueueManager._initialize_processes, bundled with rslt_q
into TaskQueueManger._workers, later unwrapped in StrategyBase but not used.
This queue is closed in TaskQueueManger._cleanup_processes.
Historically, it is passed as a init parameter into WorkerProcess,
introduced in 62d7956, but this behavior is changed in 120b9a7.
