telegraf: T3872: replace local get_interfaces() function with Section.interface()

Commit cfde4b49 ("ifconfig: T2223: add vlan switch for Section.interfaces()")
added the functionality of the local get_interfaces() function to the base
class so all other parts in the system can query for interface names of a given
type including or excluding their vlan sub-interfaces.
