get the check_ipmi_sensors output via an action

[Andrea Ieri]

The hw-health charm uses the check_ipmi_sensors script to validate the health of the server via the BMC. Whenever issues are reported, we get a rather succinct output in Nagios (due to the 1-line limitation of NRPE output), and need to log into the server to figure out what exactly is wrong.

This is usually not entirely trivial, and normally consists of the following steps:
1. ssh into the server
2. figure out which script the nrpe check actually runs
3. configure the script with the correct exclusions
4. find out how to get verbose output

I propose we write an action to automate the above. The action would simply run check_ipmi_sensors in exactly the same way nrpe does (i.e. using the charm-provided configuration options), but return verbose output.

This charm is no longer being actively maintained. Please consider using the new hardware-observer-operator instead. (https://github.com/canonical/hardware-observer-operator)
This issue is not critical, therefore, I mark it as "won't fix"
