[PATCH 1/8] terraform: Use directory checksum in SSH key filenames

[Luis Chamberlain <mcgrof@kernel.org>]

SSH keys now use directory-based checksums to support multiple kdevops
installations coexisting without conflicts. The SSH key filename format
is now ~/.ssh/kdevops_terraform_<checksum> where checksum is the first
8 characters of the SHA256 hash of the kdevops directory path.

This was previously only applied to Lambda Labs provider but is now the
default for all providers, as it solves the general problem of multiple
installations sharing the same home directory.

Also fix OCI Kconfig generation scripts to use --quiet flag correctly
to suppress progress output when generating dynamic Kconfig files.
