Add support for collapse param in Search

[BANOnotIT]

There's no method for collapse feature. Collapsing feature is vary usefull for building suggestions.

To use this feature right now in v7.0.0 of e-dsl I can use this workaround:

s = Search(...)
s = s.update_from_dict({'collapse': {'field': 'some.field'}})

It'll be much easier to use it in a way like that:

s = Search(...)
s = s.collapse('some.field', 'some.another.field')
s = s.collapse('some.complicated.field'={
  'inner_hits': ...,
  '...': ...
})
