Using jsonschema we can validate (at a basic level)
that the files created and the contents written were
not altered to be of a different format so add some
basic format validation to help in detecting format
issues/changes.
This also avoids having to use type errors to try to
detect this same kind of tampering/data format change.

Start to organize this page with a more helpful structure
that will allow people to read it and figure out which driver
best fits there usage (and to help people decide which ones
don't).

Instead of having one outlier lock class (file locks) which fetch
the same lock object from different coordinators have each coordinator
that is using the file driver return different locks and only share
the absolute minimum of components to ensure this is done in a safe
manner (due to lack of thread awareness in process based locks).

For the greater good!
People supposedly don't read the docs or warnings anyway (since people
can't read and understand capabilities of drivers they use) so this
is a best effort attempt at trying to tell people about using these.

Current we store member information in file with suffix ".raw",
To be explicit, we can skip other files, that make us add other type
information file without breaking method get_members.

The 'blocking' argument typically either means blocking as a bool
or blocking true but with the given timeout, so in various drivers they
handle this multi-type argument in nearly the same manner. To unify
that usage we can just have a utils method that breaks the multi-type
argument into its components and uniformly use that in drivers.

Certain functionality of drivers must be observed when
using a given driver (for example calling periodically
into the heartbeat method) by the user of a coordination
driver so to start with an important one explicitly
declare (and make introspectable the periodic_heartbeat
requirement that certain drivers demand to
operate correctly).

If connection fails to be established, the acquired attribute does not
exist and then you see warning such has:
Exception AttributeError: "'MySQLLock' object has no attribute 'acquired'" in
<bound method MySQLLock.__del__ of <tooz.drivers.mysql.MySQLLock object at 0x7f79479056d0>>

Running the tests on a system with IPC that does not support
non-blocking lock make the test thread fail, and then waiting forever on
the thread.
Allow the test to pass if the driver raises NotImplemented.

Distributed locks have the tendency to become acquired
and then after this point, perhaps becoming unacquired since
locks are typically on a remote machine and things like
network disconnects and such can (and do) happen causing
the running application to need an ability to check if it
is still the owner of the lock (and react appropriately).

* Remove support for python 2.6
* Remove skipsdist : Needs to be set only if
sdist is expensive
* Remove usedevelop : only needed when skipsdist
is set to True
* Remove install_command : We can just use the
default, we don't need to override

In situations where the built-in (and default) kazoo
threading async handler does not work (which sometimes
appears to happen under eventlet) allow for specifying
a different handler (ie the 'eventlet' one) that should
work better under those scenarios.

This patch adds the posibility of passing the blocking argument to the
context manager to be used when acquiring the lock.
Previous behavior will be preserved, so now we will be able to use the
context manager in any of the following ways:
with lock(10.0):
with lock(False):
with lock():
with lock:
The last 2 are equivalent.

Right now RedisLock's __init__ method is not calling its super __init__
method, as it should be doing.
It's also using attribute named "_acquired" instead of "acquired" and
creating a property name instead of using inherited name attribute like
other methods are.
This patch changes these behaviors to be consistent with other locks.
