Implemented mechanism for using distributed lock in scripting. When Redis is enabled(multi server setup) redlock distributed lock will be used. When Redis is disabled ( single server setup )  named mutex lock will be used.
In both cases the code in scripting will be the same, no need to change it.
Example of using distributed lock in scripting:

using TenForce.Execution.Scripting.Common.Concurrency;

using (ILockObject locker = DistributedLockManager.Acquire("testlock"))
{
    if(locker.IsAcquired)
    {
      //Do some work that should be synchronised
    }
}

Also DistributedLockManager.Acquire supports second optional parameter - timeout to wait in milliseconds to aquire lock.
