Alex Ellis (OpenFaaS Ltd) e33a60862d Fix vulnerability in authenticated secrets API
This patch fixes a vulnerability in the secrets API, however
it is important to stress that the user must be authenticated
as the admin user on the REST API before they can attempt this.

Reported by Appsecco via email. @lucasroesler, Appsecco and
myself believe this to be of low severity.

The fix prevents directory traversal characters from being
used in secret names. If a secret name such as:
../../root/.ssh/authorized_keys were to be used, an attacker
could remove the value and write their own.

Tested with unit tests and tests are now made to run
via the CI and a new Makefile target.
