Bjoern Rabenstein 622e8350cd Fix a bug handling freshly unarchived series. 
Usually, if you unarchive a series, it is to add something to it,
which will create a new head chunk. However, if a series in
unarchived, and before anything is added to it, it is handled by the
maintenance loop, it will be archived again. In that case, we have to
load the chunkDescs to know the lastTime of the series to be
archived. Usually, this case will happen only rarely (as a race, has
never happened so far, possibly because the locking around unarchiving
and the subsequent sample append is smart enough). However, during
crash recovery, we sometimes treat series as "freshly unarchived"
without directly appending a sample. We might add more cases of that
type later, so better deal with archiving properly and load chunkDescs
if required.

Brian Brazil e56786b221 Have scrape time as a pseudovariable, not a prometheus variable. 
This ensures it has the right timestamp, and is easier to work with.

Switch sd variable away from 'outcome', using total/failed instead.

Julius Volz 00a2a93a05 Add regression tests for metrics mutations in AST. 
It turned out in the end, that only drop_common_metrics() produced any
erroneous output in the old system. The second expression in the test
("sum(testmetric) keeping_extra") already worked in the old code, but
why not keep it in...

The way to test ranged evaluations is a bit clumsy so far, so I want to
build a nicer test framework in the end, where all the test cases can be
specified as text files which specify desired inputs, outputs, query
step widths, etc.

- Smoothed out same minor things.
