Fixes #5779

Change syslog (priority) level from LOG_NOTICE to LOG_INFO

If you look at the meaning of the different syslog levels, NOTICE means that the event may need someone to look at it. Whereas INFO is pure informational.

Since module invocations are in fact requested (deliberate) actions, they shouldn't need any additional post-processing, and therefore should not be logged as NOTICE.

This may seem like hairsplitting, but correctly categorizing system events helps weeding through the noise downhill.

According to Wikipedia: https://en.wikipedia.org/wiki/Syslog

5 	Notice 		notice 	Events that are unusual but not error conditions .
6 	Informational 	info 		Normal operational messages -no action required. Example an application has started, paused or ended successfully.

Fixes #5375

Fixes #5764

* fixed a bug in which failures from a with_* loop were not being
  caught correctly, leading to tasks continuing when they should stop
* when ignore_errors is enabled, the failure will no longer count
  towards the number of failed tasks

Merge pull request #11301 from msabramo/include_inventory_file_in_unable_to_find_inventory_file_error_msg

Add inventory file to "Unable to find" error msg

E.g.:

add simple prefix filtering to vmware inventory

Significantly speeds up inventory collection on systems with many
excluded machines.

support instances with no public ip

Avoids a race condition where previously the registered variable message
was being sent after the 'host_task_ok' message, meaning the next task
may be started before the var is registered, leading to an undefined
variable error

default to private ip if the instance doesn't have a public ip assigned. (causes list index out of range error otherwise)
