This change permits auditd logs to be ingested whether or not they begin with a node=. Previous to this change a type= was expected. It handles the case where name_format (man 5 auditd.conf) is a value other than none. Also adding 10 lines of resulting audit log with name_format = hostname parameter on CentOS 7.

Cherry-pick of PR #19659 to 7.x branch. Original message:
What does this PR do?
This change permits auditd logs to be ingested whether or not they begin with a node=. Previous to this change a type= was expected.
It handles the case where name_format (man 5 auditd.conf) is a value other than none.
Also adding 10 lines of resulting audit log with name_format = hostname parameter on CentOS 7.
Why is it important?
When running auditd with name_format other than none, the log messages will begin with node= parameter rather than type=. This behavior caused such audit logs to fail ingestion. The use case for setting name_format would be with an audit server collecting audit logs from multiple hosts.
