Add FTL-DNS cofiguration support.

Added:
* FTL-DNS configuration is now managed.

Changed:
* Updated defaults to use YAML datatypes for setupVars.conf. This is backwards
  compatible with existing configurations.
* added global pihole_disable_warning to disable warning pause when applying
  changes; allowing for consumers time to cancel role application if enabled to
  set updated configurations.
* Separated configuration to three files: main, blocklist, ftl. Most users will
  Use main; more advanced will use blocklist, and very few will use ftl.
* 'insert or ignore' migrated to 'insert or replace'; enabling management of
  the default blocklist (stevenblack); defaults updated to reflect this change.
