When exposed via a tunnel, if the underlying service is
switched, the browser remembers the / => /ui redirection
so this can be changed to a temporary redirect.

Scaling ranges keep the OpenFaaS CE gateway's requests to

OpenFaaS CE exposes metrics about function invocations and
about the gateway itself. OpenFaaS Pro has a richer set of
metrics including HTTP RED.

There is no need for OpenFaaS CE to have external auth plugins
since this added extra overhead and was never used.
OpenFaaS Pro retains the option so it can use the OIDC
auth plugin.
It's still possible, as it ever was to put a proxy in front
of any HTTP server like the gateway.
Tested with a local KinD cluster, auth still worked for the
API and UI.

This change removes the direct functions option which was
used originally for Docker Swarm. The Community Edition will
rely on the faas provider - faas-netes / faasd for load-balancing
of requests.
Direct Functions is required in order to delegate load-balancing
to Istio, Linkerd or some other kind of service mesh.
Tested by deploying a modified gateway image to a KinD cluster,
deploying the env function, and scaling to two replicas. This
balanced the load between the two pods by printing out the names
and then I ran a test with hey which returned 200s for all the
requests.
The prober which was part of the Istio support is no longer
required in the CE gateway so is removed for simplicity.

The timeout of 8 seconds was never going to be useful as
a default, so changing to 60 seconds.

* Removes service min and target metrics from the CE gateway
OpenFaaS Pro metrics are no longer required in OpenFaaS CE
since there is an OpenFaaS Pro gateway available.

Introduces a single-flight call to a function's health
endpoint to verify that it is registered with an Istio
sidecar (Envoy) before letting the invocation through.
Results are cached for 5 seconds, before a probe is
required again.
Tested without Istio, with probe_functions environment
variable set to true, I saw a probe execute in the logs.
Fixes: #1721 for Istio users.

* Add service target metric
* Add service min replicas metric

Reduce cache expiry to help support issues where a function
may be scaled down by a user, when it is still in use.
The 5s cache meant that all requests would fail until the
expiry. The 250ms setting is a 20x reduction.

This appears to have been removed inadvertently whilst
adding scale from zero logic into the gateway.
Going forward, synchronous and asynchronous calls will have a

The faas-cli throws an error because it always expects a
commit_message for the gateway version, and if it's null - it
will crash. This only affects local development.
The code in faas-cli should be changed to use a struct instead
of casting to an interface.

Enables publishing to various topics according to annotations
on the functions. The function cache is moved up one level so
that it can be shared between the scale from zero code and the
queue proxy.
Unit tests added for new internal methods.
Tested e2e with arkade and the newest queue-worker and RC
gateway image with two queues and an annotation on one of the
functions of com.openfaas.queue. It worked as expected including
with multiple namespace support.

Tested with Kubernetes on a single-node cluster, metrics
reported as expected. Existing metrics still report.
