* play, block, task: New attribute forks
With this it is possible to limit the number of concurrent task runs.
forks can now be used in play, block and task. If forks is set in different
levels in the chain, then the smallest value will be used for the task.
The attribute has been added to the Base class as a list to easily provide
all the values that have been set in the different levels of the chain.
A warning has been added because of the conflict with run_once. forks will
be ignored in this case.
The forks limitation in StrategyBase._queue_task is not used for the free
strategy.

* Handle forks in free strategy
The forks attribute for the free strategy is handled in run in the free
StrategyModule. This is dony by counting the amount of tasks where the uuid
is the same as the current task, that should be queued next. If this amount
is bigger or equal to the forks attribute from the chain (task, block,
play), then it will be skipped to the next host. Like it is also done with
blocked_hosts.

* Changing forks keyword to throttle and adding some more docs
* Fix notifying handlers by using an exact match rather than a string subset if listen is text rather than a list
* Enforce better type checking for listeners
* Share code for validating handler listeners
* Add test for handlers without names
* Add test for templating in handlers
* Add test for include_role
* Add a couple notes about 'listen' for handlers
* changelog

* make more sense
* move local function into a class method
I hastily did a copy/paste of the `async` example and it took me
a while to understand that `async` specified a maximum runtime in seconds.
The docs are actually mostly clear on this, but I made this PR while
reading the code.
This also fixes the spelling of "asynchronously".
* Fixup keyword dumping
* Clarify introductory text
* Turn links in the keyword description into seealso entries in the rst.
* Have plugin_formatter cleanup trailing whitespace
The indent filter in jinja2 < 2.10 indents blank lines by default which
leads to trailing whitespace. Cleanup after that filter.
* Edits
* Copy edit
- old functionality is still available direct lookup use, the following are equivalent
with_nested: [[1,2,3], ['a','b','c']]
loop: "{{lookup('nested', [1,2,3], ['a','b','c'])}}"
- avoid squashing with 'loop:'
- fixed test to use new intenal attributes
- removed most of 'lookup docs' as these now reside in the plugins
* Use a rst glossary for playbooks_keywords docs
* Add a 'Task' and 'Tasks' to glossary.
* Update keywords desciptions,
* use :term: rst ref, some quoting
* Make it more obvious that 'retries' and 'until' need to be used in combination.
