normalize -etcd_servers flag across all commands

The -etcd_servers flag is used inconsistently by the Kubernetes commands,
both externally and internally.

This patch fixes the issue by using the same type to represent a list of
etcd servers internally, and declares the -etcd_servers flag consistently
across all commands.

This patch should be 100% backwards compatible with no changes in behavior.

If no tag was specified, pull "latest" explicitly.

When no tag is given to Docker pull, it downloads all tags. This could be a
significantly large number of images and in the end we only ever run
:latest.
