Check boot mode to validate parameter HostNumber

[spargaon]

Identify boot mode of the system using an existing dbus service. Boot mode for Single Node [2P-Default] is 0 and it is 1 for Multi-Node [2x1P].

Check the URL for resource bios_active and parameter HostNumber. If the boot mode is Multi-Node [2x1P] and HostNumber is 0, return an error.
0 is not a valid parameter HostNumber value for the resource bios_active on Multi-Node [2x1P] systems.

Tested:
Verified on Multi-Node [2x1P] and Single Node [2P-Default] systems.

Tested on Morocco, kenya, and congo

Issue async dbus service get property request early enough for it to complete such that we have boot mode available before any URL requests for the resource bios_active with parameter HostNumber can be issued.
The boot mode property value does not after BMC boots unless specifically changed. If and when the boot mode property value is changed, BMC reboots and the dbus service fetches the new value.
In bmcweb, we can not having blocking calls to a dbus service, so issue an async call with a callback to populate
boot mode property value.

Since we know the dbus service and the property, object mapper services need not be availed but getProperty will not work since the query can not block for the response to arrive.

Return error (message) for missing, incorrect, or invalid HostNumber parameter value.

Changed to use getProperty but we still can not use dbus::utility:: for getProperty as current version does not support
getProperty and using dbus::utility::getAllProperties<uint16_t> would complicate code for no gain.

Refactored the code to eliminate a once time service and send a dbus service call as needed.

Should check boot mode only if the host number is 0

remove this line - processUpdateServiceFirmwareInventoryGet we already making call down
