krbd: support disabling auto-exclusive lock transition logic
Support an optional map argument to disable automatic exclusive lock transition upon lock request. librbd offers this via the API (and will be extended to the CLI and rbd-nbd) to support use-cases where a high-level orchestration tool wants to control which node is the owner of the lock (e.g. kubernetes HA krbd-backed RBD volumes currently use advisory locking and require admin-intervention to blacklist/break the lock upon failure).
