f5_bigip_snmp template

many issues with this zabbix template

ex : 

missing sync status

drop data with hearbeat over 6h but use data over 5min to calulate the disk size not making use of context macros just to name a few also the collected data is too frequent it will make the F5 give too much load. the usr filessytem will turn an alarm bc its standard over 90% reading the docs its normal as it is mounted readonly 

if you want i can provide the team with a improved version
