The tests for Kubernetes SD rely on comparing target groups by first
serializing them to JSON. However, the target group MarshalJSON function
only serializes the __address__ label, which makes eliminates all other
labels from the comparison.
This commit implements a separate marshaling function intended for use in
Kubernetes SD tests. The function serializes all target labels, making
comparisons much more reliable. The commit also fixes all tests that
started to fail due to the newly introduced change.

This commit introduces a new metric to count the number of failed
requests to Linode's API when using Linode SD. Resolves#10672, inspired
by #10476.
_Note_: this doens't count failures when polling the `/account/events`
endpoint, as a `401` there is how we determine if the supplied token has
the needed API scopes to do event polling vs full refreshes each
interval.

* discovery/targetgroup: support marshaling to JSON
targetgroup.Group is able to be marshaled to and from YAML, but not with
JSON. JSON is used for the http_sd API representation, so users
implementing the API were required to implement their own type which is
expected by the JSON unmarshaler.

When using Kubernetes service discovery on a Prometheus instance that's
not running inside Kubernetes, the creation of the service discovery
fails with a "no such file or directory" error as the special
`/var/run/secrets/kubernetes.io/serviceaccount/namespace` file is not
there. This commit moves the code that reads this file into the
if-branch where no `APIServer.URL` is given (that one basically makes
Prometheus assume it is running inside of a Kubernetes cluster).

When using Kubernetes on cloud providers, nodes will have the
spec.providerID field populated to contain the cloud provider specific
name of the EC2/GCE/... instance.
Let's expose this information as an additional label, so that it's
easier to annotate metrics and alerts to contain the cloud provider
specific name of the instance to which it pertains.

* Add basic initial developer docs for TSDB
There's a decent amount of content already out there (blog posts,
conference talks, etc), but:
* when they get stale, they don't tend to get updated
* they still leave me with questions that I'ld like to answer
for developers (like me) who want to use, or work with, TSDB
What I propose is developer docs inside the prometheus
repository. Easy to find and harness the power of the community
to expand it and keep it up to date.
* perfect is the enemy of good. Let's have a base and incrementally improve
* Markdown docs should be broad but not too deep. Source code comments
can complement them, and are the ideal place for implementation details.

When running tests in parallel, 10 milliseconds may not be enough for
all discoverers to register, which will make test flaky.
This commit changes the waiting logic to wait for number of discoverers
to stop increasing during given time frame, which should be large enough
for single discoverer to register in test environment.
A following run passes with this commit:

* optimize Linode SD by polling for event changes during refresh
Most accounts are fairly "static", in the sense that they're not cycling
through instances constantly. So rather than do a full refresh every
interval and potentially make several behind-the-scenes paginated API
calls, this will now poll the `/account/events/` endpoint every minute
with a list of events that we care about. If a matching event is found,
we then do a full refresh.
