Add Sla jitter packet loss percent graph (#13600)

* Add sla packet loss percent rrd graph

* Add packet loss percent div

* Add OID for NumPackets

* Fixed CDEF typo

* Rename graph file to include .inc

* Flipped axis for Src and Dst to match key

* Create new rrd file for loss percent

* Remove duplicate rrd data and rename rrd to reflect

* Amend to use second rrd file for NumPackets

* Removed spaces

* dbFetchRow be gone

* insert if statement check

* white space cleanup

* New line at end of file
