This commit moves the OpenFaaS gateway from using in-process
basic-auth for everything to use an external auth URL instead.

When auth is not enable, this functionality is not added to the
handlers and behaves as before. When enabled, the configured
plugin with authenticate requests.

Tested on Docker Swarm with positive and negative tests.

As part of #1209, this change deploys, but does not enable the
new basic-auth plugin service.

This change means the gateway is used to invoke functions
asynchronously rather than directly so that the scale from zero
path can execute.

0.12.0 moves the Prometheus port to 8082 (internal) and not
exposed on the network

This commit adds changes to run metrics server in a separate method and
also removed port 8082 from exposed port a/c to review comments.

It also uses a smaller static timeout value for new server.

**What**
- Removes the `alert` label in the scale-up alert
- Updates the annotaitons to use the `function_name` label instead of
the `instance` label that was removed.
- Per prometheus/prometheus#4836 and the related mailing list discussion
https://groups.google.com/d/msg/prometheus-users/7Ul6ngc7Ogs/j_YDszV5BwAJ


the alert value should not be included in the alert labels otherwise
each calculation of the alert is treated like a new alert and then the
use of `for 5s` will not behave as expected.
- Ports the resoltuion openfaas/faas-netes#372
