ControlCenter 2.0.0-RC8

• Primitive support for multiple processing logs from multiple Postfix servers (disabled by default)
• Initial support for interactive graphs (disabled by default)
• Updated Go dependencies
• Lots of small performance improvements

In a nutshell, this is a maintenance release, consisting on the accumulated work from the past 11 months.

ControlCenter is not actively developed anymore, as our focus as organization shifted from the Postfix monitoring space.

This will hopefully be the last RC.
