Upgrade API client to support wildcard

[elct9620]

As title, current the wildcard feature is release. It should be supported as soon as possible.

That would be great! We just need to wait for the acme-client gem to be updated to support ACME V2: unixcharles/acme-client#126

It is time to upgrade to v2, but this gem may take one or two weeks to work with it. I am busy recently.

Current I have a workable version implement, but for Wildcard support, there still have some problem.

"Wildcard only support DNS verification"

So, the gem needs a redesign.

P.S. API is changed a lot, it need rewrite too.

Update:

The Wildcard require DNS verification, and it is hard to update DNS record if we want to renew it. I think we can provide V2 API for single domain update, and integrate with other gems to support DNS verification for wildcard support. (Ex. CloudFlare)

@elct9620 when are you planning to release V2 version with single domain support? Do you have a separate branch for it?

[elct9620]

I have a V2 version branch in my local machine when I testing the wildcard feature. I will update it as soon as possible to support V2 and single domain version. And find a way to support wildcard version. 🤔
