[IMP] models.py: Method search_read propagate kwargs to read method

Currently the method `read` uses by default the parameter `load='classic_read')`
  - `self.read(fields, load='classic_read')`

So, it computes `name_get` for all m2o fields for all records in `self`.

If you want to avoid computing the `name_get` to save time and process
You can use an empty string in load parameter:
 - e.g. `self.read(..., load='')`

The method `self.search_read` call to `search` and `read` methods
but `search_read` method is not possible to assign `load=''` argument
(or other arguments of the method `read`)
 - e.g. `self.search_read(..., load='')`

So, you need to use 2 lines of code:
records = self.search(...)
records.read(..., load='')

This commit changes `search_read` method to receive all keyword arguments of the method `read`
So, you can use `self.search_read(..., load='')` and the `read` parameter will be propagated
