etcdctl: use a context with -total-timeout in simple commands

Like the commit 8ebc9331111, this commit lets simple etcdctl commands
use a context with timeout value passed via -total-timeout.

This commit doesn't change complex commands like watch,
cluster-health, and import because it is not obvious that using the
context in the commands is good or not.
