[BUG] Consistent CPU / disk usage from waagent run-exthandlers

I am seeing consistent CPU usage of 2-3% coming from the waagent; specifically:
`python -u /usr/sbin/waagent -run-exthandlers`

This is observed from top and iostat, although I haven't been able to narrow down the exact filesystem writes that are occurring.

Here is the Metrics output for my VM, showing the consistent traffic which is abnormal:

I only have the following Extensions installed on the VM:

**Distro and WALinuxAgent details (please complete the following information):**
- Distro and Version: Oracle Linux 7.7
- WALinuxAgent version
WALinuxAgent-2.2.46 running on oracle 7.7
Python: 2.7.5
Goal state agent: 2.2.46

**Log file attached**
This is verbose logging of /var/log/waagent.log, after restarting the agent.

It appears that there is some sort of repeated RunCommands occurring every few seconds which is causing this behavior, but I don't know where to look to identify why or how to resolve.
