Added ability for deferred mutator execution ()
## Changes
Added `DeferredMutator` and `bundle.Defer` function which allows to
always execute some mutators either in the end of execution chain or
after error occurs in the middle of execution chain.

Usage as follows:

```
deferredMutator := bundle.Defer([]bundle.Mutator{
    lock.Acquire()
    transform.DoSomething(),
    //...
}, []bundle.Mutator{
    lock.Release(),
})
```
In such case `lock.Release()` will always be executed: either when all
operations above succeed or when any of them fails

## Tests
