This addresses the following security issues:
* Ansible: Splunk and Sumologic callback plugins leak sensitive data in logs (CVE-2019-14864)
* CVE-2019-14846 - Several Ansible plugins could disclose aws
credentials in log files. inventory/aws_ec2.py, inventory/aws_rds.py,
lookup/aws_account_attribute.py, and lookup/aws_secret.py,
lookup/aws_ssm.py use the boto3 library from the Ansible process. The
boto3 library logs credentials at log level DEBUG. If Ansible's
logging was enabled (by setting LOG_PATH to a value) Ansible would set
the global log level to DEBUG. This was inherited by boto and would
then log boto credentials to the file specified by LOG_PATH. This did
not affect aws ansible modules as those are executed in a separate
process. This has been fixed by switching to log level INFO
* Convert CLI provided passwords to text initially, to prevent unsafe
context being lost when converting from bytes->text during post
processing of PlayContext. This prevents CLI provided passwords from
being incorrectly templated (CVE-2019-14856)
* properly hide parameters marked with no_log in suboptions when
invalid parameters are passed to the module (CVE-2019-14858)
