redlock-php - Redis distributed locks in PHP

- Forked from [redlock-php](https://github.com/ronnylt/redlock-php) by [Ronny Lopez](https://github.com/ronnylt)
- Based on [Redlock-rb](https://github.com/antirez/redlock-rb) by [Salvatore Sanfilippo](https://github.com/antirez)

This library implements the Redis-based distributed lock manager algorithm [described on the Redis website](https://redis.io/topics/distlock).

It relies on [Credis](https://github.com/colinmollenhour/credis) for Redis connections. Credis offers a native pure-PHP implementation which will automatically switch to using [phpredis](https://github.com/phpredis/phpredis) for improved performance if it's available.

To create a lock manager:

```
$servers = [
    ['127.0.0.1', 6379, 0.01],
    ['127.0.0.1', 6389, 0.01],
    ['127.0.0.1', 6399, 0.01],
];

$redLock = new RedLock($servers);
```

To acquire a lock:

```
$lock = $redLock->lock('my_resource_name', 1000);
```

Where the resource name is an unique identifier of what you are trying to lock and 1000 is the number of milliseconds for the validity time.

The returned value is `false` if the lock was not acquired (you may try again), otherwise an array representing the lock is returned, having three keys:

```
Array
(
    [validity] => 9897.3020019531
    [resource] => my_resource_name
    [token] => 53771bfa1e775
)
```

- validity, an integer representing the number of milliseconds the lock will be valid.
- resource, the name of the locked resource as specified by the user.
- token, a random token value which is used to safe reclaim the lock.

To release a lock:

```
    $redLock->unlock($lock)
```

It is possible to setup the number of retries (by default 3) and the retry delay (by default 200 milliseconds) used to acquire the lock.
