Right now promql won't time out a request if populating the iterators
takes a long time.

This changes the Walk/Inspect API inside the promql package to bubble
up errors. This is done by having the inspector return an error (instead
of a bool) and then bubbling that up in the Walk. This way if any error
is encountered in the Walk() the walk will stop and return the error.
This avoids issues where errors from the Querier where being ignored
(causing incorrect promql evaluation).

Fixes#4136
Start rule manager only after tsdb and config is loaded.
Stop rule manager before tsdb to avoid writing to closed storage.
Wait for any in-progress reloads to complete before shutting
down rule manager, so that rule manager doesn't get updated after
being shut down.
Remove incorrect comment around shutting down query enginge.
Log when config reload is completed.

Reduce the duplication of per-project specifics in the CircleCI config.
* Add docker repo variable, default to docker hub.
* Add make targets for docker push and tag latest.

Especially for Kubernetes SD, this fixes a bug where the rendered
configuration says "api_server: null", which when read back is not
interpreted as an un-set API server (thus the default is not applied).

Due to the way blocks used to overlap by 1 millisecond (see #347), when
requesting a 2-hour interval starting at `blocks[1].MinTime`, the
`Querier` would consider three blocks: `blocks[0]`, `blocks[1]` and
`blocks[2]`, because `blocks[0].MaxTime` and `blocks[2].MinTime` were in
that interval.
However, if the blocks don't overlap, only two blocks should be
returned: `blocks[1]` and `blocks[2]`. This test ensures that it's
indeed the case.

Blocks are half-open intervals [a, b), while all other intervals
(chunks, head, ...) are closed intervals [a, b].
Make that distinction explicit by defining `OverlapsClosedInterval()`
methods for blocks and chunks, and using them in place of the more
generic `intervalOverlap()` function.
This change also fixes `db.Querier()` and `db.Delete()`, which could
previously return one extraneous block at the end of the specified
interval.

Block intervals are bound by `block.MinTime`, `block.MaxTime`, but they
define a half-open interval: `[block.MinTime, block.MaxTime).
However, when deciding if a chunk was part of a block or not, the
`intervalOverlap()` function would consider both the chunk and the block
intervals as being closed.
Rather than modify the login in `intervalOverlap()`, we explicitly
remove the last value from the interval when reading from head to
persist blocks.

Previously it would set no preconditions and check no postconditions,
as the `groups` member was empty.
