hydra-queue-runner: Get store mode configuration from hydra.conf

To use the local Nix store (default):

store_mode = direct

To use a local binary cache:

store_mode = local-binary-cache binary_cache_dir = /var/lib/hydra/binary-cache

To use an S3 bucket:

store_mode = s3-binary-cache binary_cache_s3_bucket = my-nix-bucket

Also, respect binary_cache_{secret,public}_key_file for signing the binary cache.
