CI vault secrets & Kubernetes (#2)

* Define secrets that use vault plugin

* Fix drone linting issue

* Persist .kube folder as volume between build steps

* Split Build and Publish into separate pipelines

* Only run publish pipeline when triggered by main

* Import .kube/config from vault

* echo env variables contents into kube config file

* drone-vault not working, curl with token instead

* Removed all secrets, look to org secrets

* Kubernetes file

* Import dockerconfig from vault and apply as kubernetes secret
