python-common/deployment: add new tunables param to smb service spec

The tunables parameter will serve as a general configuration namespace
for small configuration adjustments that don't deserve their own full
blown config sections.
Keys should be namespaced by "topic" in order to avoid future conflicts.
Initially, this will be used for passing the ctdb debug level.
