Long: `start both a volume server to provide storage spaces

and a master server to provide volume=>location mapping service and sequence number of file ids
|
|
|
|
This is provided as a convenient way to start both volume server and master server.
|
|
The servers acts exactly the same as starting them separately.
|

So other volume servers can connect to this master server also.

Optionally, a filer server can be started.

Also optionally, a S3 gateway can be started.
