* config: set target group source index during unmarshalling
Fixes issue #4214 where the scrape pool is unnecessarily reloaded for a
config reload where the config hasn't changed. Previously, the discovery
manager changed the static config after loading which caused the in-memory
config to differ from a freshly reloaded config.

This adds support for basic authentication which closes#3090
The support for specifying the client timeout was removed as discussed in https://github.com/prometheus/common/pull/123. Marathon was the only sd mechanism doing this and configuring the timeout is done through `Context`.
DC/OS uses a custom `Authorization` header for authenticating. This adds 2 new configuration properties to reflect this.
Existing configuration files that use the bearer token will no longer work. More work is required to make this backwards compatible.

For special remote read endpoints which have only data for specific
queries, it is desired to limit the number of queries sent to the
configured remote read endpoint to reduce latency and performance
overhead.
Currently all read queries are simply pushed to remote read clients.
This is fine, except for remote storage for wich it unefficient and
make query slower even if remote read is unnecessary.
So we need instead to compare the oldest timestamp in primary/local
storage with the query range lower boundary. If the oldest timestamp
is older than the mint parameter, then there is no need for remote read.
This is an optionnal behavior per remote read client.

* k8s: Support discovery of ingresses
* Move additional labels below allocation
This makes it more obvious why the additional elements are allocated.
Also fix allocation for node where we only set a single label.
* k8s: Remove port from ingress discovery
* k8s: Add comment to ingress discovery example
* Add openstack service discovery.
* Add gophercloud code for openstack service discovery.
* first changes for juliusv comments.
* add gophercloud code for floatingip.
* Add tests to openstack sd.
* Add testify suite vendor files.
* add copyright and make changes for code climate.
* Fixed typos in provider openstack.
* Renamed tenant to project in openstack sd.
* Change type of password to Secret in openstack sd.
Allow namespace discovery to be more easily extended in the future by using a struct rather than just a list.
Rename fields for kubernetes namespace discovery
Each remote write endpoint gets its own set of relabeling rules.
This is based on the (yet-to-be-merged)
https://github.com/prometheus/prometheus/pull/2419, which removes legacy
remote write implementations.
