From the documentation:
> The default HTTP client's Transport may not
> reuse HTTP/1.x "keep-alive" TCP connections if the Body is
> not read to completion and closed.
This effectively enable keep-alive for the fixed requests.

ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives.
iii) Does away with the use of fmt package for errors in favour of pkg/errors

rewritten to support the new versions of the library. miekg additionally
claims this is more correct in the ticket.

Currently Prometheus requests show up with a UA of Go-http-client/1.1
which isn't super helpful. Though the X-Prometheus-Remote-* headers
exist they need to be explicitly configured when logging the request in
order to be able to deduce this is a request originating from
Prometheus. By setting the header we remove this ambiguity and make
default server logs just a bit more useful.
This also updates a few other places to consistently capitalize the 'P'
in the user agent, as well as ensure we set a UA to begin with.

By default, OpenStack SD only queries for instances
from specified project. To discover instances from other
projects, users have to add more openstack_sd_configs for
each project.
This patch adds `all_tenants` <bool> options to
openstack_sd_configs. For example:
- job_name: 'openstack_all_instances'
openstack_sd_configs:
- role: instance
region: RegionOne
identity_endpoint: http://<identity_server>/identity/v3
username: <username>
password: <super_secret_password>
domain_name: Default
all_tenants: true

Commit 1c89984 introduced the ability to expose the owner of the instance.
However, this breaks Prometheus if there is no OwnerID in the reservation (Eg. if you are using a private EC2-API introduced by #4333)
