Heavy refactoring of formula.

Add dictsort to dict iterations to avoid modification of orders to see
modifications easier.
Use only one formula for configuration, no more config and config-pt.
The remaining formula use pillar with map every time.
Set some sections, Default in fail2ban.conf and Definition in
custom filters and custom actions, it make pillar easier to read.
