Get model using command line tool

Get the PSU model using a command line tool specified in the meson
options. The default tool is 'psutils --get-model'. The tool should
get the model data directly from the PSU.

This is more accurate than getting the Model property of the Asset
interface on D-Bus. Inventory Manager saves its state to files. When
the BMC is booted, Inventory Manager initializes itself using the saved
state. This is necessary to handle the scenario where the BMC is
rebooted while the rest of the system is powered on (such as a
concurrent BMC code update).

However, if all power was removed from the system, a PSU may have been
added/removed/replaced while the BMC was offline. When the BMC boots,
the Inventory Manager saved state is not correct.

Eventually the PSU monitoring application will update the model on
D-Bus, but this can take a non-trivial amount of time. This is
especially true if EntityManager is used to provide the PSU bus and
address information to the PSU monitoring application.

Tested:
* Verified all automated tests build and run successfully
* Verified application uses command line tool to obtain model
* Verified command line tool was returning the correct model
* Test where command line tool fails with non-zero exit code
* Tested where all PSU information available when application starts
* Tested where PSU information is obtained after application starts
using the InterfacesAdded handler
* Tested where PSU presence changes and is obtained by the
PropertiesChanged handler
* Full test plan is available at

generate-psu-tar: Add machine name and remove single "-" options

Remove single "-" options because there are too many similar options.

The openbmc image manager expects "MachineName" in MANIFEST that matches
the BMC's OPENBMC_TARGET_MACHINE in /etc/os-release.
* If there is no MachineName in MANIFEST, it logs a warning for now;
* If they do not match, an error is reported and the version is deleted.

Add --machineName argument for generate-psu-tar to make it support the
"MachineName".

Tested: Verify that when a correct machine name is given, the tarball is
processed by image manager correctly;
And if an invalid machine name is given, the tarball uploaded
will get "Machine name doesn't match" error and is deleted.
