Chris Lu e537852ec6 Support multiple filers for S3 and IAM servers with automatic failover
This change adds support for multiple filer addresses in the 'weed s3' and 'weed iam' commands, enabling high availability through automatic failover.

Key changes:
- Updated S3ApiServerOption.Filer to Filers ([]pb.ServerAddress)
- Updated IamServerOption.Filer to Filers ([]pb.ServerAddress)
- Modified -filer flag to accept comma-separated addresses
- Added getFilerAddress() helper methods for backward compatibility
- Updated all filer client calls to support multiple addresses
- Uses pb.WithOneOfGrpcFilerClients for automatic failover

Usage:
  weed s3 -filer=localhost:8888,localhost:8889
  weed iam -filer=localhost:8888,localhost:8889

The underlying FilerClient already supported multiple filers with health
tracking and automatic failover - this change exposes that capability
through the command-line interface.
