Significantly improve efficiency of indexing by simplifying and removing regex from props.conf and transforms.conf.
Add url and filename fields and fix major_content_type field
Change field threat_id to threat_name.  Fix threat_id and report_id to match only the numerical identifier in the threat_name.
Content Dashboard: fix issues with data not showing up.
Removed remaining references to "index=pan_logs".  Now the `pan_index` macro is always used, so if you want to change the name of the index, you only need to change it in macros.conf.
Update to latest panxapi (pan-python) library with better support for user-id and ip registration errors.
Support new fields in PAN-OS 6.0, including pcap_id and file_digest
Reverse part of `pan_index` macro commit because macros can't be used with 'collect' command.

Updated datamodel to use new WildFire Report XML format version 2.0
When both src_user and dst_user are NULL, set 'user' to 'unknown'.  This allows for better handling of dashboard data.
