* make hash_params more robust in the face of many corner cases
Fixes#18680
Alternative fix to #18681
* add test case for role.hash_params
* Add role.hash_params test for more types
A set, a generator/iterable, and a Container that
is not Iterable.
(cherry picked from commit 5f5ea06ca4)
* Make sure include_role inherit variables from parent role
Setting the parent of task blocks generated by include_role after they
have been produced is not sufficient - it means the tasks don't have the
correct dependency chain set afterwards, and therefore, don't properly
inherit variables from outer roles.
In addition to manually setting the parents, pass the dep_chain when
compiling the role, such that variables are correctly imported.
Fixes#18540.
* Add tests for include_role
* Fix include_role variable inheritance for multiple parent levels
(cherry picked from commit 57f4a9885e)
also remove condition to bypass setting user if user matches current user
this enables forcing user when set to the same user as current user and ignoring .ssh/config
while keeping .ssh/config with current user if nothing is specified.
* allow global no_log setting, no need to set at play or task level, but can be overriden by them
* allow turning off syslog only on task execution from target host (manage_syslog), overlaps with no_log functionality
* created log function for task modules to use, now we can remove all syslog references, will use systemd journal if present
* added debug flag to modules, so they can make it call new log function conditionally
* added debug logging in module's run_command
Due to the way we're now calculating delegate_to, if that value is based
on a loop variable ('item') we need to calculate all of the possible
delegated_to variables for that loop.
Fixes#12499
Also making PlayContext a child class of the Playbook Base class,
which gives it access to all of the FieldAttribute code to ensure
field values are correctly typed after post_validation
Fixes#11381
