Explore naming properties based on functionality instead of where the functionality runs

[keith-turner]

Some properties in Accumulo related to functionality like compactions are named based on where that functionality runs. For example compactions used to all run in the tablet server, so lots of compaction related properties had a tserver prefix. In the elasticity branch where functionality is running is moving around. It may be better to name properties based on functionality instead of where the functionality runs. For example have a top level compaction prefix for compaction related properties instead using the tserver prefix.

Need to perform a survey of properties and see how many could be adjusted.

[ddanielr]

A top level compactionprefix has been added and compaction related tserver prefixes have started to be deprecated and removed.

One consideration is if the property is mutable or not and how that might change property groups.
