Restv2 feature branch merge to master (#284)

Move to new REST v0.2 communication between front and back-end.   This is a first cut implementation which is functional, but will need follow-up enhancements for performance, error checking, etc.    Protocol spec is in docs directory.

* Add filtering via indexing

* Using new filter specs

Indexing working

* Added filtering by annotation value

* factor out common methods

* Documentation

* create enum for axis (obs/var)

* Better description for filter's return

* Add boolean to enumerated types

* Augmented enum for scanpy axis

* Create schema for annotations

Based on datatype within scanpy/anndata
+ tests

* remove obsolete schema parse script

* Update rest api to remove old routes and add schema route

* Separate development requirements

* Warning for unsupported datatypes

* include -r requirements.txt in dev

* Merged downcast warnings

* Fixed bug where names were NaNs

Needed to include the index too when creating the series

* Add config endpoint

* Generate app features from CLI selections

* Move features to driver

* Add tests for schema

* Clearer version wording

* python3 version of super

* version from engine to package level

* move features to driver

* Revise layout function to match the new spec

* GET for layout/obs

* PUT Layout (#211)

* PUT Layout

* Csweaver/annotations (#212)


* Update scanpy engine to support the rest v0.2 annotation requests

* GET endpoint for obs annotations + tests

* Documentation

* Test annotations in scanpy engine

* Description for annotation-keys param

* annotation->annotations

* clarified return for annotations

* Use URL query list for annotations fields

* parse_filter parses v0.2 GET filters (#215)

* parse_filter parses v0.2 GET filters

* Don't allow index filters from query params

* Better variable conversion

* Parse filter improvements

- uses default dict
- renamed filter -> query_filter

* Cleanup Tasks (#216)

* Add test_api back into travis build

* Do custom JSON encoding the correct way

* Run cellxgene server in test setup

* Cleanup new tests too

* Option to bind to all interfaces (#225)

app.run("0.0.0.0") instead of app.run("127.0.0.1") binds to all interfaces.

Note: There are comments on the internet that says that the flask server is not up to the task of production serving.  I don't think that such scalability concerns apply here, but I was able to get cellxgene working with twistd relatively easily, and we could switch to that if there are scalability concerns.

Test plan: browsed to <ip>:5005/api/v0.2/config on a different host.
