Freenom dns provider and Nightly-Certes library

Features:

• Add Freenom dns provider with using Skidbladnir.Client.Freenom.Dns

Fixes:

• Change configuration from ext method for IConfiguration, to config class and bind configs from IConfiguration
• Expand validate try count and BadNonce try count
• Transferred to the unstable version of the Certes package (Nightly-Certes), which implements retrying requests with an invalid Nonce due to a too late validation request.
• Up selenium version

Beta version of DotNetCertBot

Beta version of certbot for issuing certificates for free domains (freenom: mk, cf, ml, etc.) via Dns Challenge CloudFlare.
Done:

1. Let's Encrypt ACME
2. Cloudflare dns api based on Selenium and User Web Interface (because cloudflare disabled the ability to manage dns via api zones for free domain names)
3. Build into a docker container and into a single executable file (for windows and linux)
