v0.6.12

registry tool plugins, enforcing lower-case restrictions on resource names

• Following AIP-122, we require that resource names be lowercase.
• Assorted improvements were made to the registry tool's linter plugin
• A new kubectl-style plugin mechanism was added that, for example, allows registry-experimental subcommands to be called from the registry tool with registry experimental.
