Consul
------
**Driver:** :py:class:`tooz.drivers.consul.ConsulDriver`
**Characteristics:**
:py:attr:`tooz.drivers.consul.ConsulDriver.CHARACTERISTICS`
**Entrypoint name:** ``consul``
**Summary:**
The `consul`_ driver is a driver providing only distributed locks (for now)
and is based on the consul server key/value storage and/or
primitives. When a lock is acquired it will release either when explicitly
released or automatically when the consul session ends (for example if
the program using the lock crashes).
