Make possible to ban yqla\qt

This PR makes it possible to ban qt\yqla. This may be useful for rolling updates, as it will allow us to avoid running new queries on old instances. YqlAgent in banned state stops accepting new queries, but continues to process old ones. QueryTracker in banned state stops accepting incoming API calls and stops taking new queries from Active Queries table, while still processing old ones. --- Pull Request resolved: ytsaurus/ytsaurus#851 commit_hash:126cf666fc066779f3d6c80296ed9bcd5e6651cc
