v0.3.4

Description

This release delivers some speed improvements through caching plugins and
not running terraform workspace select unnecessarily. In my testing it saves ~20s per run.

Features

• All config flags can now be specified by environment variables. Fixes (#38).
  • Completed thanks to @psalaberria002!
• Run terraform with the TF_PLUGIN_CACHE_DIR env var set. Fixes (#34).
  • This will cache plugins and make terraform init faster. Terraform will still download new versions of plugins. See https://www.terraform.io/docs/configuration/providers.html#provider-plugin-cache for more details.
  • In my testing this saves >10s per run.
• Run terraform with TF_IN_AUTOMATION=true so the output won't contain suggestions to run commands that you can't run via Atlantis. (#82).
• Don't run terraform workspace select unless we actually need to switch workspaces. (#82).
  • In my testing this saves ~10s.

Bug Fixes

• Validate that workspace doesn't contain a path when running ex. atlantis plan -w /jdlkj. This was already not a valid workspace name according to Terraform. (#78).
• Error out if ngrok is already running when running atlantis bootstrap (#81).

Backwards Incompatibilities / Notes:

• None
