Aaron Goulet 8c4efc83e1 refactor: Updated graphs to use safer RRD check (#6781)
Graphs that were using `file_exists()` to check for the presence of RRD
files now use `rrdtool_check_rrd_exists()` instead. This is a fix for
distributed poller configurations that are running `rrdcached` on a
different host.
