* Remove graph_types from DB.
This is silly since defining them in definitions.inc.php already does the same thing.
Adds missing ones in definitions.inc.php and rewrites others since I already wrote them before I realized they were duplicates.
* remove dead table
* Remove graph_types inserts from schema files.
* update db_schema.yaml

While this creates the graphs under Apm for the F5s, there is no data. I can pull the data manually. Maybe I have the definition incorrect in includes/polling/os/f5.inc.php?
snmpget -m /opt/librenms/mibs/f5/F5-BIGIP-APM-MIB -v 3 -u <user> -l authPriv -a SHA -A <password> -x AES -X <password> <server> apmAccessStatCurrentActiveSessions.0
F5-BIGIP-APM-MIB::apmAccessStatCurrentActiveSessions.0 = Wrong Type (should be Counter64): Gauge32: 1245
or maybe it's because the OID has the incorrect type in it, although the result is actually correct.
