Add Ecobee services

[hudcap]

Enable/disable automatic daylight savings time
Enable/disable the Alexa mic on the Ecobee 4
Enable/disable Smart Home/Away and follow me modes

Proposed change

This enables additional services for the Ecobee.

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New integration (thank you!)
• New feature (which adds functionality to an existing integration)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

Additional information

I did not add tests since a) that looked daunting, and b) there were other Ecobee services that didn't have tests.
However, I did manually test all the added services on my existing HA installation and they all worked properly on my Ecobee.
I can probably figure out how to add tests if necessary.

Checklist

"Local tests pass" -- are these the tests that will run automatically after creating the PR?
Sorry for my ignorance -- I'm comfortable in Python, but I mainly write my own code, so all these guidelines and formats sound awesome, but are a little overwhelming :)

• The code change is tested and works locally.
• Local tests pass. Your PR cannot be merged unless tests pass
• There is no commented out code in this PR.
• I have followed the development checklist (I think so...)
• The code has been formatted using Black (black --fast homeassistant tests) (formatted using Black in VSCode -- not sure what to make of that command)
• Tests have been added to verify that the new code works.

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

• Documentation added/updated for www.home-assistant.io

If the code communicates with devices, web services, or third-party tools:

• The manifest file has all fields filled out correctly.
  Updated and included derived files by running: python3 -m script.hassfest.
• New or updated dependencies have been added to requirements_all.txt.
  Updated by running python3 -m script.gen_requirements_all.
• Untested files have been added to .coveragerc.
