Ability to enable/disable debug mode per OpenStack service

Add ServiceDebug parameters for each services that will allow operators
to enable/disable Debug for specific services.

We keep the Debug parameters for backward compatibility.

Operators want to enable Debug everywhere:
  Debug: true
Operators want to disable Debug everywhere:
  Debug: false
Operators want to disable Debug everywhere except Glance:
  GlanceDebug: true
Operators want to enable Debug everywhere except Glance:
  Debug: true
  GlanceDebug: false

New parameters: AodhDebug, BarbicanDebug, CeilometerDebug, CinderDebug,
CongressDebug, GlanceDebug, GnocchiDebug, HeatDebug, HorizonDebug,
IronicDebug, KeystoneDebug, ManilaDebug, MistralDebug, NeutronDebug,
NovaDebug, OctaviaDebug, PankoDebug, SaharaDebug, TackerDebug,
ZaqarDebug.

Note: for backward compatibility in Horizon, HorizonDebug is set to
false, so we maintain previous behavior.
