Better formatting for usage template. Group commands in usage to management/operation commands. Remove the word Docker from the description of management commands. Signed-off-by: Daniel Nephin <dnephin@docker.com>

var volumeDescription = `
|
|
The **docker volume** command has subcommands for managing data volumes. A data
|
|
volume is a specially-designated directory that by-passes storage driver
|
|
management.
|
|
|
|
Data volumes persist data independent of a container's life cycle. When you
|
|
delete a container, the Engine daemon does not delete any data volumes. You can
|
|
share volumes across multiple containers. Moreover, you can share data volumes
|
|
with other computing resources in your system.
