Add 'rename' property to field types. This causes the field to be renamed when within an Object signature. For example, the following signature expects to get {'foo': '...'} out of GET and LIST requests and to take in {'foo': '...'} on PUT and POST

SIGNATURE = sepiida.fields.Object(s={
'foo' : sepiida.fields.String(),
})

but we can change that to expecting {'bar': '...'} out of GET and LIST and taking in {'bar': '...'} from POST and PUT without changing the signature as it is viewed from the outside world

SIGNATURE = sepiida.fields.Object(s={
'foo' : sepiida.fields.String(rename='bar'),
})

This can be very useful for creating complex field types which I'll do more of in future releases

---
Automatically convert UUIDs provided to sepiida.storage module. This is just a convenience for clients so they don't have to any more

---
Update build script to auto deploy new updates to PyPI

---
* Add options method to json client for testing options requests.
* Make schema serialization automatically convert things to string, if possible, to avoid crashing when we need to do things like make the 'choices' parameter for a signature field an object that doesn't have a defined translation to JSON. Which is nearly everything

Fix bug where we didn't pass through credentials when doing a retry

---
sepiida now automatically propogates credentials through and sepiida.backend.task. Also, we set up a task context so that we can correctly use sepiida.requests.user_session in either the frontend or backend code and still get a session that has the credentials from the user
