* Hardened flatten-and-reduce-config through sorting of :auth and
:website vectors
* add issuer kv and volume-size kv only when existing in config
* fixed test in website_test.cljc
* fixed content-vol-creation for nonexistent volume-size kv pair
Also fixed smaller issues in website.cljc.
Better division of generate-common-*, now these functions
may reside in c4k-common and generate standing ingresses/certs
with only service and fqdn inputs (which need to be set anyways).
Also moved predicates and specs to website.cljc.
It seems, that an auth file is necessary for conf creation.
So added a dummy file containing one key value pair.
Also update of names and formati in configmap and deployment.
Also added valid_config and valid auth.
