* 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.

##### SUMMARY
This page is very confusing and may suggest, that there is still a `serial` strategy (like it used to), but now it is just a directive of `linear` strategy. Multiple people reported this to me and it needs change.

* Add a few examples of how to correctly use `regex_replace` filter
because it behaves differently on different Python versions when using
regex qualifiers that can match an empty string (e.g. '*', '?', etc).
Often when I am helping others learn Ansible, they are using nodes spun up on Amazon/Google/etc. where private key files (pem) are needed. Mentioning just a bit more on how to handle those private key files on the intro_getting_started page will help more folks get started faster.
I even reviewed the changes with my learning team and they all agreed this helped clarify immediately for them how to really get started with Ansible from a practical perspective.
