A high number of concurrent queries can slow each other down
so that none of them is reasonbly responsive. This commit limits
the number of queries being concurrently executed.

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.
