Previously, the struct `testTargetRetriever` had hardcoded active and dropped targets. This made it difficult to change the target information depending on the test case.
This change introduces a way to define them as arguments and pass it to a constructor for building. It lays a foundation for dynamically defining targets with various set of arguments to test different scenarios.

* Add time units to storage.tsdb.retention.size flag
In an effort to reduce confusion with the `m` option of the
`ParseDuration()` function, this commit adds the available time units to
the `storage.tsdb.retention.time` flag to help showcase that there is no
option for months (which could be assumed to be `m`).
If someone were looking to set the retention to six months, they may
mistakenly do so with `6m`, which would reduce their retention to six
minutes.

The Kubernetes client records workqueue duration and latency metrics as
seconds so there's no need to convert the values from microseconds to
seconds anymore.
The cache metrics (prometheus_sd_kubernetes_cache_*) are removed because
they aren't used anymore by the client though still exposed by its API.

For sanity I'm not going to try to distinguish the things I'm maintainer
for because I'm the right person (e.g. template) vs things I'm the
maintainer for because someone has to be (e.g. pkg). Also add a general
warning to handle that this is more nuanced than it's worth trying to
capture, and relatedly always going to be out of date.
I'm also not giving full names/emails as we do elsewhere, as that'd
make things only more difficult to read for this particular repository.
I didn't put Bartek down for remote read, as particular functions of
particular files seems a a bit fine grained.

* promql: Allow injecting fake tokens into the generated parser
Yacc grammars do not support having multiple start symbols.
To work around that restriction, it is possible to inject fake tokens into the lexer stream,
as described here https://www.gnu.org/software/bison/manual/html_node/Multiple-start_002dsymbols.html .
This is part of the parser rewrite effort described in #6256.

For yacc generated parsers there is the convention to capitalize the names of item types provided by the lexer, which makes it easy to distinct lexer tokens (capitalized) from nonterminal symbols (not capitalized) in language grammars.
This convention is also followed by the (non generated) go compiler (see https://golang.org/pkg/go/token/#Token).
Part of the parser rewrite described in #6256.

This is the first step towards a generated lexer as described in #6256.
It adds methods to the parser struct, that make it implement the yyLexer interface required by a yacc generated parser, as described here: https://godoc.org/golang.org/x/tools/cmd/goyacc .
The yyLexer interface is implemented by the parser struct instead of the lexer struct for the following reasons:
* Both parsers have a lookahead that the lexer does not know about. This solution makes it possible to synchronize these lookaheads when switching parsers.
* The routines to handle parser errors are not accessible to the lexer.

It is possible that desired shards is always a bit higher than the
number of shards (less than 30%) and by exporting desired shards as the
raw number it will be easy to tell if a Prometheus is in that situation.

When using both a label and the suffix+label in the
relabel config. It's possible that Prometheus remove
the suffx+label for no obvious reason. It's due to a
collision when merging labels from target and from
the sample.

It's currently causing weird unknown problems in React tests that run
successfully everywhere else, and by now all the tests that run on
Travis also run on CircleCI, so Travis is not needed anymore.

* promql: Clean up parser struct
The parser struct used two have two somewhat misused fields:
peekCount int
token [3]item
By reading the code carefully one notices, that peekCount always has the value 0 or 1 and that only the first element of token is ever accessed.
To make this clearer, this commit replaces the token array with a single variable and the peekCount int with a boolean.

The "green" status of this badge was actually last updated 4 years ago,
until I manually ran a master branch test today that made the current
Travis test failures in the React tests visible. But those test failures
seem to be Travis-related and not real (the same tests pass on
CircleCI). Maybe we can completely remove Travis by now, but let's
remove the now-failing badge for now to not scare users.

* React UI: Fix tests harder
Again not sure why this passed last time (?), but now I was getting an
error about 'NaN' not being a valid value to assign to the 'height'
property of the input element. This changes it so that only the blur()
function is actually mocked out on the active input element.

* Fixup
Signed-off-by: Julius Volz <julius.volz@gmail.com>
Before this commit, the PromQL parser ran in two goroutines:
* The lexer goroutine that splits the input into tokens and sent them over a channel to
* the parser goroutine which produces the abstract syntax tree
The Problem with this approach is that the parser spends more time on goroutine creation
and syncronisation than on actual parsing.
This commit removes that concurrency and replaces the channel by a slice based buffer.
Benchmarks show that this makes the up to 7 times faster than before.
