Adjust snmp translation to return conversion info. Also consolidated the translation code to obtain all info with just 1 command execution. Also split test command mocks out to their own file for cleanliness.

Fix snmp overriding of auto-configured table fields (#4208) Whenever the snmp plugin was configured with a table with automatic field discovery, if one of those fields was explicitly overridden in the config and the value of is_tag was changed, the field would be duplicated, once as a tag & once as a field. This change fixes the behavior so that if a field is explicitly configured, automatic table field discovery doesn't touch it.
