Add ecovacs component (home-assistant#15520)

* Ecovacs Deebot vacuums

* All core features implemented

Getting fan speed and locating the vac are still unsupported until sucks adds support

* Move init queries to the added_to_hass method

* Adding support for subscribing to events from the sucks library

This support does not exist in sucks yet; this commit serves as a sort of TDD approach of what such support COULD look like.

* Add OverloadUT as ecovacs code owner

* Full support for Ecovacs vacuums (Deebot)

* Add requirements

* Linting fixes

* Make API Device ID random on each boot

* Fix unique ID

Never worked before, as it should have been looking for a key, not an attribute

* Fix random string generation to work in Python 3.5 (thanks, Travis!)

* Add new files to .coveragerc

* Code review changes

(Will require a sucks version bump in a coming commit; waiting for it to release)

* Bump sucks to 0.9.1 now that it has released

* Update requirements_all.txt as well

* Bump sucks version to fix lifespan value errors

* Revert to sucks 0.9.1 and include a fix for a bug in that release

Sucks is being slow to release currently, so doing this so we can get a version out the door.

* Switch state_attributes to device_state_attributes
