[FEATURE REQUEST] Set protocol for Vault only in one place in configuration

[erzetpe]

Is your feature request related to a problem? Please describe.
We should be able to set protocol for Vault only in one place, not like in the config below:

---
kind: configuration/vault
title: Vault Config
provider: aws
name: default
specification:
  vault_enabled: true
  ...
  **tls_disable: true
  externalVaultAddr: http://external-vault:8200**

This can lead to inconsistency and confusing bugs.

Describe the solution you'd like
I would like to have protocol - http or https configured only in one place.

Describe alternatives you've considered

It has been tested. The protocol selection (http / https) now depends on the value of the tls_disable parameter and the vault address is built based on it.
