Add ATEN PE component for ATEN eco PDUs

[mtdcr]

Description:

This component integrates ATEN power distribution units. A PE8324 was used for development. It fetches configured names from the PDU and creates a switch for each outlet. Communication is done via SNMP.

Pull request with documentation for home-assistant.io: home-assistant/home-assistant.io#11301

Example entry for configuration.yaml, using SNMPv3:

switch:
  - platform: aten_pe
    host: mypdu.lan.
    auth_key: !secret mypdu_authkey
    priv_key: !secret mypdu_privkey

Checklist:

If user exposed functionality or configuration variables are added/changed:

The label "docs-missing" can be removed now.

I approve, however, I want to have a more experienced reviewer to have a final call.
