Custom config directory and automatic authentication
This commit adds two new provider features: 1. Ability to specify a custom config_dir. This is useful for keeping LXD configurations in a shared directory. 2. Ability to authenticate to an LXD server. This provides the ability to not have to authenticate to a new LXD server out-of-band of Terraform.
