Brian Brazil 29e8dc2c49 promql: Add 'bool' modifier to comparison functions 
When doing comparison operations on vectors, filtering
sometimes gets in the way and you have to go to a fair bit of
effort to workaround it in order to always return a result.
The 'bool' modifier instead of filtering returns 0/1 depending
on the result of the compairson.

This is also a prerequisite to removing plain scalar/scalar comparisons,
as it maintains the current behaviour under a new syntax.

Brian Brazil fb585e4591 promql: Remove interpolation of vector values. 
The current behaviour produces values that are not
from rules or scrapes. So if for example I have
a boolean 0/1 it can be returned as 0.2344589. This
prevents a number of advanced use cases, introduces
race conditions and can produce misleading graphs.

Fabian Reinartz 690b5f1575 Remove multi-statement queries 
This commit removes the possibility to have multi-statement queries
which had no full support anyway. This makes the caller responsible
for multi-statement semantics.
Multiple tests are no longer timing-dependent.

Fabian Reinartz cb10ceac18 promql: allow scalar expressions in range queries, improve errors. 
These changes allow to do range queries over scalar expressions.
Errors on bad types for range queries are now raised on query creation
rather than evaluation.

beorn7 3b9c421a69 Weed out all the [Gg]et* method names. 
The only exception is getNumChunksToPersist to avoid naming the struct
member numChunksToPersist in a weird way.

Fabian Reinartz 9ab1f6c690 Limit maximum number of concurrent queries. 
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.
