* Update terraform_validate.sh:
-Change to the directory before running terraform validate to use the Terraform
configuration for the appropriate working directory.
* Neglected to change the terraform validate call to use the default of the
current directory.
* Several changes to improve functionality:
- Switch to checking the path for '*.tf' instead of always checking the current
directory.
- Try to find a '.terraform' directory (which indicates a `terraform init`) and
change to that directory before running `terraform validate`.
* Fix the description for the terraform_validate hook to reflect changes that were
made in:
35e0356188
* - Clean up comments.
- Adjust variable names to better reflect what they are holding.
