A few days ago, we added validation for namespaces. We've decided to expand these naming rules to include containers. To facilitate this, a common package `identifiers` now provides a common validation area. These rules will be extended to apply to task identifiers, snapshot keys and other areas where user-provided identifiers may be used. Signed-off-by: Stephen J Day <stephen.day@docker.com>
