Allow every synced field to be used as an integration data point (Meraki)

Integrations show more synced fields on an asset than can be mapped to a layout field. For example, the Meraki card on a firewall shows Mac, Name, Model, Serial, WAN1 IP, WAN2 IP, Address, Firmware, latitude, longitude and Configuration Last Updated At. When setting the Integration data point on a text field, the only choices are device_display_name, device_ip_address, device_mac_address, device_model, device_serial_number and device_type.

• Make every field an integration syncs available as an integration data point.

• Example: map Meraki Firmware to a Firmware Version field, and WAN1 / WAN2 IP to public IP fields, so they stay current instead of being typed in by hand.

• Apply the same to other integrations' synced fields.
