Add support for git-crypt

What

Add support for git-crypt.

Why

git-crypt is commonly used to encrypt secrets like IP addresses or access tokens in Git repositories containing Infrastructure as Code descriptions (such as Terraform ones).

It is recommended to use private repositories with Atlantis. However, due to the distributed nature of Git, each contributor of a Terraform project has a copy of its repository, including all the secrets it contains. Using git-crypt would prevent unauthorised access to these sensitive data in case of one of the project contributors' laptop is being stolen for example.

git-crypt can be used by specifying a custom run step: https://www.runatlantis.io/guide/atlantis-yaml-use-cases.html#running-custom-commands

Will this work for you?
