add delta transfomer support
this patch adds support for a delta transformer. the transformer's
only functionality is to calculate the delta between current sample
and previous sample.
conditions:
- it will disregard any out of order samples
- a growth_only param is available to capture only positive deltas
- supports renaming to a new meter name using same schema as other
transformers.
using this transformer, we also create a cpu.delta meter which will
enable another view of cpu meter. this delta meter will allow for
(relatively) accurate cputime calculations and will cope with cputime
resets.
