This commit adds a new 'keep_firing_for' field to Prometheus alerting
rules. The 'resolve_delay' field specifies the minimum amount of time
that an alert should remain firing, even if the expression does not
return any results.
This feature was discussed at a previous dev summit, and it was
determined that a feature like this would be useful in order to allow
the expression time to stabilize and prevent confusing resolved messages
from being propagated through Alertmanager.
This approach is simpler than having two PromQL queries, as was
sometimes discussed, and it should be easy to implement.
This commit does not include tests for the 'resolve_delay' field. This
is intentional, as the purpose of this commit is to gather comments on
the proposed design of the 'resolve_delay' field before implementing
tests. Once the design of the 'resolve_delay' field has been finalized,
a follow-up commit will be submitted with tests."

* Update docs example rules for default config
The prometheus download includes a default config to scrape itself.
This self-scraping prometheus doesn't include any metric named as
`http_inprogress_requests`, but does include one named
`prometheus_http_requests_total`.
Updating this example rule in the docs to one which can be used
out-of-the-box with the default download would be a nice improvement.

Since the struct defines proxy_connect_header instead of proxy_connect_headers, all relevant occurences of it were replaced with the correct configuration name as defined in the HTTPClientConfig struct.

Currently, it's not explicitly called out which permissions are needed
for service discovery of EC2 instances. It's not super hard to figure
out, but it did involve a bit of guesswork when I did it yesterday, and
I figure it's worth saving people that effort.
I've also seen examples around the internet where people are granting
much broader permissions than they need to, so maybe we can save on that
by explicitly saying what's needed.

It's currently possible to use blackbox_exporter to probe MX records
themselves. However it's not possible to do an end-to-end test, like is
possible with SRV records. This makes it possible to use MX records as a
source of hostnames in the same way as SRV records.
