Add support for collecting data for BMC dumps
When occ-control receives a USR1 signal, it will trigger the code to
collect the following data:
- number of OCC objects created
- for each active OCC: state, role, hwmon path, poll response, and WOF
data
The data will be written in JSON format to a file which can be collected
and added to a dump. (/tmp/occ_control_dump.json)
To force the data collection:
killall -s SIGUSR1 openpower-occ-control
