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
header populated.

This commits updates version endpoint to use ProviderInfo and VersionInfo structs from
faas-provider.GatewayInfo now uses ProviderInfo and VersionInfo structs. GatewayInfo is
left within gateway. Consumer of this endpoint should use typed struct GatewayInfo to
parse response.

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.

The call is much faster now, so this request should me made
at a lower frequency.
Also adds error handling for URL building in the external

This patch changes the code which looks up service and appends
them to the Exporter's list. It previously would create an
endless list and cause a memory leak.

* Updates AngularJS to 1.8.0
* Updates the MaterialUI theme to 1.2.1
* Fixes: #1576
Tested by running the gateway locally, with NATS, Prometheus,
and a gateway port-forwarded from a local KinD cluster.
The UI rendered and the newer files were served. Functions
could be deployed and invoked from the store and CLI.

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.
