[client] Feature/upload bundle

[mlsmaycon]

Describe your changes

Add an upload bundle option with the flag --upload-bundle; by default, the upload will use a NetBird address, which can be replaced using the flag --upload-bundle-url.

The upload server is available under the /upload-server path. The release change will push a docker image to netbirdio/upload image repository.

The server supports using s3 with pre-signed URL for direct upload and local file for storing bundles. You can configure them with the following environment variables:

# S3
# bucket to generate pre-signed url
BUCKET
# region needed to generate presigned url
AWS_REGION
# if not using rules or similar:
AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY

# Local file store

# server URL to build upload URL for client to send data
SERVER_URL
# store directory (defaults to /var/lib/netbird
STORE_DIR
