increase number of open files for collectd
for collectd KPIs we need may need to open 10,000+ files one file for each core * number of CPU counters we read. Use the ansible pam_limits moules to increase the nofile setting. This should allow the VNF to boot with increased number of files open Change-Id: I46b75d5ca59e8e359c985a1e37daaee89897884c Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
