Serverless reverse proxy implementation

[0xean]

Background

we need a basic reverse proxy for 0x and zerion

some sort of serverless infra should be utilized for this.

https://www.serverless.com/ has been offered as a good solution for simple lambda abstraction

Acceptance Criteria

1. implement basic reverse proxy for 0x / zerion, test all critical endpoints called by the shapeshift app
2. determine proper secret storage (can we use GH secrets) and access (how do we rotate keys)
3. CI/CD process for updates
4. ping @0xean for adding cnames / cloudfront
5. endpoints should restrict origin
6. rate limiting by ip would be nice to have, but could also be done in CF
7. write lambda in TS
