cert-mon is not supported by the patch-restart-processes script

[Ghada Khalil]

Brief Description
-----------------
cert-mon is not supported by the patch-restart-processes. This makes it more difficult to patch this process as an in-service patch.

Severity
--------
Minor - it's still possible to patch-back cert-mon as an in-service patch, but more code is required. See the Workaround section.

Steps to Reproduce
-------------------
Examine the patch-restart-processes script

Expected Behavior
-----------------
cert-mon should be supported by the script

Actual Behavior
---------------
cert-mon is not supported by the script

Reproducibility
---------------
100% reproducible

System Configuration
--------------------
any

Branch/Pull Time/Commit
------------------------
stx master (but also in r/stx.5.0)

Last Pass
---------
Never

Timestamp/Logs
---------------
N/A

Workaround
----------
Add code to restart the service as part of the patch-restart script. Similar to this example:
