[ldez]

• have a homogeneous design with the other providers
• pass the linter
• do go mod tidy
• add tests (units)
• add tests ("live")
• add a provider descriptor
• generate CLI help, documentation, and readme.
• be able to do: (and put the output of this command to a comment)

rm -rf .lego/

HOSTTECH_API_KEY=xxx ./lego -m your_email@example.com --dns hosttech -d *.example.com -d example.com -s https://acme-staging-v02.api.letsencrypt.org/directory run

Note the wildcard domain is important.

@RealFriesi could you test by running the previous command (you have to use a real domain and email)?

Closes #1437

I will test it out today as soon as I get home

🤔 Maybe it's related to the Content-Type header, I updated the code, you can try again.
