Field migration: host.id -> hw.serial_number

[tsellers-r7]

Description

This PR implements the change discussed in Issue #364.

The changes:

• changes host.id to hw.serial_number where the value is a hardware serial number
• changes host.id to host.name where the value references a host name
• in each case where there is a vendor specific serial number field such as cisco.serial_number that value is duplicated in hw.serial_number and a test added for it.

Motivation and Context

The intent is to add clarity to the data that is captured. The field host.id was unclear and was being used to capture hostnames as well as serial numbers.

How Has This Been Tested?

rspec, fingerprint example captures.

I agree with changing to hw.serial_number as a consistent field, but there may be some adjustment needed on the Rumble side (if not Nexpose too).
