terraform init wrapper - backend switch and environment name export.
#!/usr/bin/env bash
#
# This script is used for configuring terraform and it's remote state backend
# for a specific environment. This is done by sourcing a backend config in the
# `dev` folder under the git root directory. Note that the backend config file
# name needs to end with a `.hcl` extension and the file basename is used as
# the environment name provided. It also sets a `TF_VAR_envname` with the
# environment name as value.
#
# For distinguishing the different environments the script also sets `PS1`.
