Fixes https://github.com/home-assistant/home-assistant/issues/4389

The USB address of these devices periodically changes, causing
home-assistant to fail to read the temperature data. This PR fixes this
by re-reading the available devices on failure. I've been running this
for several days and for the first time have consistent temperature
data without having to restart home-assistant.

* Fix polling of NestCamera

* Lint

* Expose isort preferences for tools.

* Adhere to pylints sorted imports requirement.

* More documentation, set typing in between stdlib and 3rd party.

This lets components declare their precision for temperatures. If
nothing is declared, we assume 0.1 C and whole integer precision in
F. Currently this supports only WHOLE, HALVES, and TENTHS for
precision, but adding other precision levels is pretty straight
forward.

This also uses proliphix as an example of changing the precision for a
platform.

Closes bug #4350

* Tweak services return result

* Lint

Allow generic thermostat tolerance to be customisable to determine the temperature difference required to turn switch on. (#4585)

Remove fixed throttle for binary_sensor.command_line and sensor.command_line since the scan_interval is configured trough YAML since #1059 (#4586)

* LiteJet: Unit tests and new trigger options held_more_than and held_less_than.
* Unit tests for the LiteJet component and associated platforms. Coverage is almost 100% -- just misses one line.
* The automation LiteJet trigger returns an empty "removal" function to ensure the automation base is happy with it. The pylitejet library doesn't actually support a real removal.
* The automation LiteJet trigger can detect hold time and act appropriately to support things like short tap or long hold.

* LiteJet: Fix indent in unit test source code.

* LiteJet: Fix test_include_switches_* unit tests on Python 3.5

* LiteJet: Remove wait for state existence from unit tests. Recent fixes to discovery make this no longer necessary.

This addition could be usefull when working with the template sensor using the data of this sensor.

* Use string formatting, add link to docs, and pylint

* Extent platform for validation
