This PR introduces both breaking changes and the following features for bulk importing data into the Fastly KV Store.

The breaking changes introduced in this PR are the rename of the --key-name flag to --key to be consistent with the other 'stores' supported within the CLI.

NOTE: The first two approaches require the value to be base64 encoded as they are being streamed to a Fastly 'batch' API endpoint. The last approach (directory structure) makes individual "set-value-for-key" calls that are processed concurrently.

# stdin
echo '{"key":"example","value":"VkFMVUU="}' | fastly kv-store-entry create -s olwenufofbiklsaaz4i1l8 --stdin

# file
#
# {
#   "key": "file-example-1",
#   "value": "VkFMVUU="
# }
# {
#   "key": "file-example-2",
#   "value": "VkFMVUU="
# }
fastly kv-store-entry create -s olwenufofbiklsaaz4i1l8 --file data.json

# directory
# filename == key, file contents == value
fastly kv-store-entry create -s olwenufofbiklsaaz4i1l8 --dir ./data/

Each example is documented in pkg/app/metadata.json.
