This issue is to track the work for adding common fields among different host metrics. These proposed common fields (eventually) will become required fields to collect when adding support for new host type.

Proposed Common Fields:

• host.id
• host.name
• host.cpu.pct
• host.network.in.bytes
• host.network.in.packets
• host.network.out.bytes
• host.network.out.packets
• host.disk.read.bytes
• host.disk.write.bytes

TODO:
For each Metricbeat module listed below, we need to investigate if all proposed common fields are collected. If they are, we should duplicate these fields and change to use the names from above. If there are missing fields, we need to add them in the module first.
