Brian Brazil f34de493d5 Add increase() function, to replace delta(..., 1). 
This calculates how much a counter increases over
a given period of time, which is the area under the curve
of it's rate.

increase(x[5m]) is equivilent to rate(x[5m]) * 300.

Fabian Reinartz 5602328c7c Refactor query evaluation. 
This copies the evaluation logic from the current rules/ package.
The new engine handles the execution process from query string to final result.
It provides query timeout and cancellation and general flexibility for
future changes.

functions.go: Add evaluation implementation. Slight changes to in/out data but
	not to the processing logic.
quantile.go: No changes.
analyzer.go: No changes.
engine.go: Actually new part. Mainly consists of evaluation methods
	which were not changed.
setup_test.go: Copy of rules/helpers_test.go to setup test storage.
promql_test.go: Copy of rules/rules_test.go.
