Add `DocstoreFn` - lookup doc via arbitrary function (#3760)
This **partially** addresses
https://github.com/hwchase17/langchain/issues/1524, but it's also useful
for some of our use cases.

This `DocstoreFn` allows to lookup a document given a function that
accepts the `search` string without the need to implement a custom
`Docstore`.

This could be useful when:
* you don't want to implement a `Docstore` just to provide a custom
`search`
 * it's expensive to construct an `InMemoryDocstore`/dict
 * you retrieve documents from remote sources
 * you just want to reuse existing objects

wip: add method for both docstore and embeddings (#119)
this will break atm but wanted to get thoughts on implementation.

1. should add() be on docstore interface?
2. should InMemoryDocstore change to take a list of documents as init?
(makes this slightly easier to implement in FAISS -- if we think it is
less clean then could expose a method to get the number of documents
currently in the dict, and perform the logic of creating the necessary
dictionary in the FAISS.add_texts method.
