Extend startuptime in collectd's pmon config file

Browse Source 
The maintenance Process Monitor (pmond) experiences a spawn
timeout while restarting or recovering the collectd process
over a failure in Debian.

Collectd's current process monitor config file startuptime is 3 secs.

Collectd version 5.8.1 spawn time in CentOS is very quick, ~1 sec
 log example: collectd spawned in 1.000 secs
 centos rpm : collectd-5.8.1-4.el7.x86_64

Collectd version 5.12.0 spawn time in Debian is 3-6 seconds
 log example: collectd spawned in 6.000 secs (also 3,4,5 secs)
 debian pkg : base-bullseye.lst:collectd  5.12.0-7

It seems the new version of collectd in the Debian environment
takes longer to spawn, exceeding the current 3 second timeout.

This update extends the collectd pmon config file startuptime
to 10 seconds to account for this version and environment change.

Test Plan:

PASS: Verify collectd process manual restart with new startuptime in
      - both CentOS and Debian and on both vbox and real hw
PASS: Verify collectd process kill recovery with new startuptime in
      - both CentOS and Debian and on both vbox and real hw

Regression:

PASS: Verify soak of collectd process restart 50+ loops
PASS: Verify soak of collectd process recovery 50+ loops
PASS: Verify process manual restart of all pmon monitored processes
PASS: Verify process kill recovery of all pmon monitored processes
