feat(retry-on-timeout): Implement retry on timeout when creating new client

[MathieuGuillet]

Add new options and instructions to implement retries on timeout when the pool tries to create new client in the pool.

This will avoid to throw an error on the first timeout error if it can be recover in a given time.

I think library users should be able to achieve this by calling the relevant pool function repeatedly as long as it returns a specific type of error (which might be different types of errors according to different needs). You can write a module for that.
