Title: Allow for custom params processing before each operation is executed

This is done via configuring the middleware:

```ruby
config.middleware.use BatchApi::Middleware do |c|
c.params_processor = lambda do |params|
params.except(:hacky_param)
end
end
```

If no processor is specified, the params won't be changed.
