This change allows functions to be "idled" or scaled to zero
replicas and then be invoked later on. There is a penalty to
scaling up - the API gateway proxy will block until the function
is ready.

A cache is included to off-set the calls to upstream API to check
on readiness along with unit tests.

Testing via scaling to zero replicas and then invoking function.
On Swarm I observed 3 seconds on an Intel Nuc i5 for scaling back
from zero replicas.

- basic_auth is now set to true by default unless overriden
in the env-var "BASIC_AUTH"

Signed-off-by: Alex Ellis (VMware) <alexellis2@gmail.com>

The deployment script will enable basic-auth by default to help
avoid people deploying to a public IP with no protection from
malicious actors.

- In deploy_stash.sh /dev/random can hang on some systems, so using
  urandom will give a better experience, if less "random" data.
  For the purposes of creating an initial basic auth password this
  is sufficient.
- Alpine Linux does not have the shasum command, but sha256sum.
- Tested on MacOS with and without --no-auth flag.
- Does not apply for armhf or powershell.
