Revamp certbot init

[nemchik]

• Resolves incorrect handling of cpanel dns plugin introduced in Dns updates #277 by using correct new syntax and CLI arguments. Fixes cpanel plugun not working after rollback to 1.32.0 #303
• Resolves newly required CLI arguments for directadmin plugin version 1.0.3 (and newer). Fixes [BUG] Directadmin DNS doesn't seem to work #307
• Apply string replacements for dns plugin confs to renewal file /config/etc/letsencrypt/renewal/${ORIGDOMAIN}.conf, also rearrange script to keep existing string replacements for user config next to string replacements for renewal file. Fixes Cert renewal via Gandi DNS plugin fails #296
• Move revocation logic up, mostly to keep cert issuing logic and preceding variable assignment closer together.
• Rewrite PREFCHAL section
  • Almost all dns plugins use the same syntax for CLI arguments, so standardize the expected arguments and handle exceptions more specifically
  • route53 and standalone do not support setting a credential file via CLI argument (route53 credential file is defined using AWS_CONFIG_FILE in the Dockerfile)
  • azure, gandi and standalone do not support setting a propagation time via CLI argument
  • cpanel uses non-standard parameter naming conventions that will very likely be deprecated and fully removed in a future release of certbot (maybe already done in 2.0) but for now it can be used if handled specifically
  • duckdns works like most other standard plugins, but we add an extra CLI parameter (no-txt-restore) to prevent issues when using local DNS records (see Use --dns-duckdns-no-txt-restore flag #293)
