Add Simply.com as DNS Provider

[mrwee]

Is your feature request related to a problem? Please describe.
I would like to have DNS Provider support added for Simply.com so I can use wildcard certificates. I cannot right now, since they are not supported by NPM.

Describe the solution you'd like
Simply.com added as DNS Provider so I can use DNS Challenge for Let's Encrypt. They have a simple API which other applications also use.

Describe alternatives you've considered
It's difficult for me to change DNS prodivider, due to: It's free of charge, already use other applications which utilize their API.
