Add DNS provider for Com Laude

[ldez]

Closes #2880

Ping @lackern-se-digicert, can you run the command with your domain, credentials, etc. (and put the output of this command to a comment)?

make build
rm -rf .lego

COMLAUDE_USERNAME="xxx" \
COMLAUDE_PASSWORD="yyy" \
COMLAUDE_API_KEY="zzz" \
COMLAUDE_GROUP_ID="abc" \
./dist/lego --dns comlaude -d '*.example.com' -d example.com -s https://acme-staging-v02.api.letsencrypt.org/directory run

Note that the wildcard domain is important.

Thank you for your patience to review the request, unfortunately, I do not have direct access to the privilege information required to run the commands.

OK, but why have you asked for the addition of this provider? 🤔

Perhaps you could ask someone to test the PR?
