Feature Request to add ZoneEdit support to LetsEncrypt Add-on

1. Brief description of the device or service.
Add ZoneEdit to list of supported LetsEncrypt DNS providers. Unfortunately I don’t have the time to validate that these scripts work and to make a pull request once done. I’m betting that those that have been working the letsencrypt addon will be far more well versed in how the DNS verification is done and will be able to quickly add ZoneEdit support with the provided repo below.

2. Link to the provider or manufacturer’s product or service page.

**3. Link to the service or device’s API, along with information as to whether it is public or requires an account or key. (This is extremely important because without a published API, integration of any device or service will be difficult if not impossible!)

4. Any other relevant information including examples or GitHub repositories related to the device or service.
