* outsourcing env variable setup This commit contains major parts of the work of refactoring the setup and usage of environment variables. It outsources the setup into its own script and provides dedicated functions to be executed at a later point in time. A **new** env variable was added: `USER_PROVISIONG` which provides a better way of defining which method / protocol to use when it comes to setting up users. This way, the `ENABLE_LDAP` variable is deprecated, but all of this is backwards compatible due to a "compatibility layer", a function provided by the new variables script. This is not a breaking change. It mostly refators internal scripts. The only change facing the user-side is the deprecation of `ENABLE_LDAP`. We can prolong the period of deprecation for this variable as long as we want, because the new function that ensures backwards compatibility provides a clean interface for the future.
